Tuesday, September 4th, 2018 Author: With every new release of the Mac operating system, there always seems to be a few installation errors that are encountered by enough people to make us wonder how the OS managed to get through the beta process. The answer can usually be attributed to the difference in the relatively small number of beta users versus the large number of users downloading and installing a new official release of the macOS.

When all those new users start to install the OS, the sheer number of Mac hardware, peripherals, and software makes it very likely that some bug that managed to sneak through the beta process will rear its ugly head in the release version. (No matter which version of the macOS you’re installing, including 10.14 Mojave, there’s a slight chance you may run into one of the problems in this guide.) In this guide, we’re going to look at some of the installation problems that tend to occur with new releases of the Mac operating system. With any luck, you may be able to either correct the issue, allowing you to finish the installation, or prevent the issue from occurring in the first place. Installation Issues Commonly Seen with macOS Before we get too far along, I want to point out the obvious: don’t install a new version of the Mac operating system without having a current backup.

Some of the installation issues we’re going to mention can cause loss of data. Having a or a can be a lifesaver. If you don’t have a backup system in place, I highly recommend investing in one before you install a new version of macOS. You can find a large number of, and, as well as a portable and easily-carried-with-you high performance USB 3 or Thunderbolt bus-powered SSD storage. With the backup recommendation out of the way, let’s get started with the error messages. Could Not Write Installation Information to Disk This message usually shows up as a sheet that drops down from the macOS or OS X installer shortly after you start the install process.

It may seem odd but the usual cause is a corrupt installer, and simply deleting the installer app and downloading a new copy will likely fix the issue. The error message seems to occur most often when the Mac installer is downloaded from a third-party site. This is a good reason to download the official copy from the Mac App Store, or join the free public beta program if you want to try out a new version of the Mac OS early. (You can use Disk Utility to repair common boot drive errors that may be keeping you from successfully finishing an installation.) Other possible causes include a damaged boot drive. Try using Disk Utility’s First Aid capabilities to test and repair your disk, as outlined in: Could Not Find Installation Information for This Machine You may run across this error message when you’re performing a clean install of the Mac OS and have erased the startup drive. Normally, when you perform a clean install and erase the startup drive, you do so while running the macOS installer from another boot drive, perhaps.

Here's the error I get trying to run 'pokemon pikachu' after installing pokemon-terminal with pip3 Traceback (most recent call last): File '/Library/Frameworks/Python. I need a script that is able to find all the errors (see 'Using rsync from Terminal' - Variable errMsg), without stopping his work, and display the outputs (Variable 'risultato'). New Applescript try.

If the installer has a problem, you may find yourself forced to reboot and use the Recovery Partition or the Internet Recovery System built into your Mac. It’s at this point that the Could Not Find error message is displayed. The usual cause is a simple one; your Mac isn’t connected to your local network and the Recovery process is trying to access Apple’s servers to download the software needed for installation. Instead of telling you your Wi-Fi or Ethernet network isn’t working, the installer displays the above message. The fix is to make sure you’re connected to your Ethernet network, or have your Wi-Fi password on hand. Restart your Mac while holding down the Command + R keys to enter recovery.

(Once you have an Internet connection, the macOS Recovery utility should be able to complete the reinstall process.) If you don’t automatically connect to your network, you’ll be asked to either supply the Wi-Fi password or select another method of connecting to your network. If you connect by Wi-Fi, make sure it’s selected, and then supply the password. You should now be able to continue the. Computer is Incompatible with the Operating System You Are Attempting to Install This error message is an oldie, but could be seen by someone upgrading from OS X Yosemite and earlier to OS X El Capitan or later. Start by checking to see if your Mac is actually compatible with a newer version of the OS. In some cases, you won’t be able to upgrade because Apple has dropped support for your older Mac. You can check the compatibility lists at the links below.

If your Mac is listed as compatible, you’re running OS X Yosemite or earlier, and you’re still seeing the error message when you attempt to upgrade, chances are your startup drive’s permissions need to be repaired. (Macs running OS X Yosemite and earlier may need the startup drive’s disks permissions repaired before updating to a newer version of the Mac OS.) You can find instructions on repairing disk permissions in the article:. MacOS Could Not Be Installed on Your Computer This is a similar problem to the incompatible error listed above, except it involves all Macs running macOS Sierra and later.

Just as before, start by making sure your Mac is compatible with the macOS version you’re installing. You can use the same links listed above to check compatibility. Once you’re sure your Mac is on the compatibility list, it’s time to check your time, or more specifically, your Mac’s time and date settings. A rather obscure issue with the Date & Time preferences can prevent installation of a new version of the macOS.

Launch System Preferences by selecting the System Preferences icon in the Dock, or by selecting System Preferences from the Apple menu. Open the Date & Time preference pane.

Make sure the date and time are set correctly. Be sure to verify that the time zone is also correct. To make changes, you’ll need to unlock the padlock with your administrator password. Make any changes needed to ensure the settings are correct. If you have a reliable Internet connection, it’s best to use the option to “Set date and time automatically.” Use the dropdown menu to select a local Apple timeserver. (Something as simple as the Date and Time being incorrectly set can prevent a Mac OS installation from completing.) If you’re not able to access the System Preferences to fix the time and date issue, you can do so from the Recovery system by using the Terminal app, which is available from the Recovery menu. You can find instructions for using the Recovery system in the article:.

The instructions for using Terminal to make time changes are available in:. When All Else Fails There are a number of generally helpful troubleshooting tips that can get a wayward installation back on track. While not tied to a specific installation process, these tricks have been known to correct an underlying issue and get a Mac user going again: First Aid: Run a First Aid repair of your startup drive (assuming the startup drive is the target of your installation). Follow the instructions in: Safe Mode: You should also consider starting up in Safe Mode. Safe Mode will perform some basic system checks, including testing your Mac’s hardware, startup disk, and system software. It will also disable most third-party extensions that may be interfering with the installation process:.

Startup Disk settings: Once in a while, the Mac’s startup disk can be set incorrectly because of an installation error. When this happens, the installation won’t be able to complete because it will attempt to boot from the wrong drive. If you’re having install problems you can’t figure out, use System Preferences, Startup Disk to check that it’s set correctly. Reset NVRAM and SMC: The NVRAM (early Macs used PRAM), combined with the SMC, holds a great deal of the Mac’s system settings.

Sometimes these settings can get out of whack, and have unusual effects on a system installation, not to mention causing your Mac to be a bit goofy in general. Resetting them to their default states can sometimes correct issues you may be having. You can find out more in the article:. At this point, you should have been able to fix the installation issue you may have encountered.

If not, it may be time to restore your Mac’s data from your backup, and take a fresh start at installing your new or updated OS. How about this (going from 10.13.4 to 10.13.6): “An error occurred while loading the installer resources” Oddly (or, not so, because Apple.) enough no error message was written to the install.log. System.log says (heavily trimmed) systemstats51: assertion failed: 17E199: systemstats + 914800: 0x40 com.apple.xpc.launchd1: Caller not allowed to perform action: plugin-containe.525 but what does this mean?

I do know 17E199 is the kernel for macOS 10.13.4. Maybe a sandboxing problem?

And probably the assertion failure has no connection to the launchd error. The Mojave beta installer will reformat your hard drive, if you’re using one, to APSF. That doesn’t mean that the final release will do so, but there’s no way to prevent it at the moment. The script you could use with High Sierra doesn’t work with Mojave. Of course, if you’re installing on an SSD this isn’t a problem.

But APSF doesn’t work well on a mechanical hard drive. Not right now, anyway. This isn’t an issue on a Fusion Drive (I hope), as APSF won’t install, though, supposedly, Mojave will. So there’s even more to look out for with the Mojave upgrade. I’ll be reading the fine print. And watching what happens to early adoptors.;-) My workaround was to clone the Mojave beta to an HFS+ partition and run it from there.

So, this is just one more issue to watch out for. Unless I hear of a change I’ll be installing the release version of Mojave on a test platform, just as I’ve doen with the beta. You leave out the pain that will be encountered if you have a tower MacPro 5,1.

You will need to purchase a new video card that is Metal-compatible, appropriate card power connectors from eBay, and shut off FileVault. Recent Posts.

Ever try to delete a file and get an Access is Denied error? Or maybe you’re trying to copy or move a file or folder and you get a message stating the source file may be in use? This type of error can occur for several reasons: you do not have ownership of the file or folder and therefore cannot perform any actions on it or the operating system or another program is currently using it.

You can usually figure out which situation you’re involved with by taking a look at what exactly you’re trying to do. If you get the Access is Denied or You don’t currently have permission to access this folder message, then you’re probably looking at a permissions problem. If you’re not an Administrator on the computer, you’re probably not going to be able to fix this issue, so first make sure you can get access to an admin account. Access Is Denied Error This particular error is normally caused by NTFS permissions, but it can also be caused by other issues like a corrupt user profile, encryption on the file or if the file is in use. We’ll talk about file in use errors in the next section. To gain access to the file or folder, you’ll need to have the correct permissions configured for your account.

Before you start doing any work, you should try to click on the Continue button that will show up in Windows 7 and Windows 8 automatically. This will try to give your user account permissions to the folder as long as you are the owner. If you get the You have been denied permission to access this folder message after clicking Continue, that means you are not the owner and you’ll have to first take ownership of the folder before you can change any permissions.

Take Ownership of Files and Folders in Windows Taking ownership is unfortunately quite a process, so it’s best to have ample time and patience before attempting this. To get started, you need to right-click on the file or folder, choose Properties and then go to the Security tab. If you have no access to the folder, you’ll see a message stating you have to be an Administrator to view the security properties. Go ahead and click on Continue. This will pop up another dialog where you get the option to change the owner.

In the Change owner to box, select your user account or Administrators. I personally choose my own account because that’s the default behavior in Windows when you create a new folder/file.

Also make sure to check the Replace owner on subcontainers and objects box. Click OK and you’ll get another message saying you don’t have permissions to read the contents, do you want to replace permissions and grant yourself Full Control. Now make sure to click OK on any remaining open windows so that all dialogs are closed. Don’t try to change any other settings at this point. You have to first close any open dialogs and go back to the Explorer screen. Once there, again right-click on the file/folder and choose Properties and go to the Security tab. It should now look a bit different.

You can access the contents of the file/folder at this point, but it’s best to reset the permissions completely. At this point, you have just added yourself and that’s it. If you want the default Windows permissions that would be applied, you can follow the next couple of steps. Click on the Advanced button and then click on Change Permissions. Click the Remove button and remove all of the permissions currently listed. At this point, it should just be your user account. Once the listbox is empty, go ahead and check the Include inheritable permissions from this object’s parent box.

Then click the Apply button, not the OK button. You should see several entries appear in the listbox, including one for your user account.

The default permissions also include SYSTEM and Administrators usually, so it’s a good idea to reset them properly this way. If the folder has many sub-folders with files, you can check the Replace all child object permissions with inheritable permissions from this object box.

Close all dialogs and you should be good to go! As I mentioned earlier, Access is Denied can be caused in some cases by other issues. A corrupt user profile is one of those odd issues that I have seen more in domain environments. You can create a new user profile and then try to access the file or folder. The other issue is if the file is encrypted. You can always try checking to see if the file is encrypted or not by right-clicking and choosing Properties. Then click on the Advanced button from the General tab and uncheck the Encrypt contents to secure data box.

If someone else has encrypted the file/folder, you won’t be able to access it until you can decrypt it using their user account. The last issue if the file itself is corrupt. In that case, you will have to search for software that can help repair corrupt files, though this is a very rare cause of the problem. File in Use or Sharing Violation Error Note that getting the Access is Denied message can be caused by a sharing violation, so if the above method did not work, try the following procedure below.

You can download and install a free program called from Microsoft. You can use it to find out which processes are locking up a file. Right-click on the executable file after unzipping and choose Run as Administrator to run the program. Then don’t worry about all the crazy colors and bars, just go to the top and click on Find and then Find Handle or DLL.

Now type in the name of the file in question in the box and type search. You don’t have to type the full name of the file; just part of it will also work most of the time. You should get back a list of processes that currently have locks on the file. In my case, Notepad.exe locked my test document. Now select the item in the box and then close the search box. You should be back at the main process explorer screen.

At the bottom, a row should be highlighted and it should be the path to the file that you had selected in the search box. Right-click on that row and choose Close Handle. If there was more than one process in the search box, you will have to repeat the same procedure for each process. At this point, you should be able to delete or modify the file as you please. The program is very useful when you get these types of error messages:.

Cannot delete file: Error 5 Access is denied. There has been a sharing violation.

The source or destination file may be in use. The file is in use by another program or user. Make sure the disk is not full or write-protected and that the file is not currently in use Program is very lightweight and does not take up very many resources at all. It can also tell you a lot of other information about Windows processes, but that’s for another post. Like I said above, if someone has denied you access manually, you will not be able to get into that folder or file unless you are given permissions from an Administrator!
