Jan 22, 2020 4. Fixing The “Cannot Sign-In Into Music or TV App” Bug Using Your Mac’s Terminal. This method worked for us, and our thanks go to Serge Rosenthaler for his post on the Apple forums. Now just a head’s up, you will need to use the Terminal on your macOS Catalina to carry out the steps below. Aug 29, 2018 You can do it in Terminal by typing (or copying and pasting) this command and then hitting Enter: killall Dock. The Dock should restart itself automatically. Note: If you don’t want to use the terminal, you can accomplish the same thing by restarting your system—it just takes more time. The Slightly Less Simple Fix: Reset and Restart Your Dock.

The following is the same task outlined above, except it’s done through the Terminal application of the Mac.

Disk Utility User Guide
Disk Utility can fix certain disk problems—for example, multiple apps quit unexpectedly, a file is corrupted, an external device doesn’t work properly, or your computer won’t start up. Disk Utility can’t detect or repair all problems that a disk may have.
If you run First Aid on a disk, Disk Utility checks the partition maps on the disk and performs some additional checks, and then checks each volume. If you run First Aid on a volume, Disk Utility verifies all the contents of that volume only.
- In the Disk Utility app on your Mac, choose View > Show All Devices.Note: If you’re checking your startup disk or startup volume, restart your computer in macOS Recovery, select Disk Utility in the macOS Utilities window, then click Continue. If you check your startup volume (Macintosh HD), make sure you also check your data volume (Macintosh HD - Data).
- In the sidebar, select a disk or volume, then click the First Aid button .If Disk Utility tells you the disk is about to fail, back up your data and replace the disk—you can’t repair it. Otherwise, continue to the next step.
- Click Run, then click Continue.If Disk Utility reports that the disk appears to be OK or has been repaired, you’re done. You can click Show Details to see more information about the repairs. Otherwise, you may need to do one of the following.
- If Disk Utility reports “overlapped extent allocation” errors, two or more files occupy the same space on your disk, and at least one of them is likely to be corrupted. You need to check each file in the list of affected files. Most of the files in the list have aliases in a DamagedFiles folder at the top level of your disk.
- If you can replace a file or re-create it, delete it.
- If it contains information you need, open it and examine its data to make sure it hasn’t been corrupted.
- If Disk Utility can’t repair your disk, or you receive a report that the First Aid process failed, try to repair the disk or partition again. If that doesn’t work, back up as much of your data as possible, reformat the disk, reinstall macOS, then restore your backed-up data.

One of the best things about a Mac is the range of free apps that come pre-installed. However, that doesn’t mean you won’t download and install other applications from time to time. It should be easy — like most Apple tasks — but that isn’t always the case. This post explains what you can do if your Mac won’t install apps.

Quick Tips
Try out these quick tips to update or install new apps on your Mac, or read the full post for more details:
- After trying to open a new app, go to System Preferences > Security & Privacy to allow it.
- Update macOS and reboot your Mac to resolve all manner of related problems.
- Delete the app from your Mac and install it again from scratch.
- Temporarily turn off your firewall from System Preferences > Security & Privacy.
Common error messages when installing Mac apps
When trying to download or update apps, you might get one of the following messages:
- “App can’t be opened because it is not from the App Store.”
- “App failed to download. Use the Purchases page to try again.”
- “The application could not be downloaded. The installation could not be started.”
If this, or something similar, has happened to you, we have the solution below. But first, let’s make sure you’ve got the basic requirements to install an app.
What do you need to install apps on a Mac?
In order to download, install, or update an app on your Mac you will need the following three things:
- a good Internet connection
- ample free storage
- an administrator password.
Check your Internet connection by streaming a video online. If the video is slow to load, contact your Internet service provider for assistance. Cofee-microsoft forensic tools fixed.
Check your storage by clicking the button in the menu bar and selecting About This Mac > Storage. Ensure you have at least as much space as recommended by the app developer. Preferably a bit more.
You’ll often need an administrator password to complete the installation of an app. If need be, ask the administrator to log on and install the app themselves. Otherwise, they may need to enter their password when prompted from your account.
How do I open apps that aren’t from the App Store?
Macs benefit from a lot of in-built safety precautions, but when downloading third-party apps they can sometimes appear overzealous. By default, your Mac won’t install apps from anywhere other than the App Store, although this is easy to bypass.
After downloading an app, control-click the file in your Downloads folder and select Open from the menu. You’ll get the same ‘unidentified developer’ warning as before, but this time you’ll have the option to open the app anyway.
You can reduce the frequency of these alerts by going to System Preferences > Security & Privacy > General. Click the padlock and enter your administrator password to unlock the settings, then choose to “Allow apps downloaded from: App Store and identified developers.”
Update macOS and reboot your Mac to reduce issues
Update macOS to the latest version, unless it isn’t compatible with the app you’re trying to use. Developers typically list the recommended operating software wherever you download the app from.
Check for updates in macOS by clicking the button in the menu bar and selecting About This Mac > Software Update.
A reboot of your Mac is another effective troubleshooting tool. Shut down your Mac using the button in the menu bar, and leave it powered off for a minute or so before powering on again. After doing so — and allowing all the background processes to close down and start again properly — your Mac is likely to run with fewer issues.
Delete the app and then try to install it again.
Run Mac App In Terminal
Before deleting any apps from your Mac you should make sure you have a recent backup of all your valuable data.
It could be that the app, or the app installer, has become corrupt and this is why your Mac won’t install or update it. The only remedy for this is to remove the app from your machine entirely and download it again from scratch.
Close down any version of the app if it is currently running on your Mac by using the Quit [App] button in the menu bar. Then open Finder and go to the Applications folder, find the relevant app and drag it to the Trash.
You should check the Application folders for individual users on your Mac. This can be done by navigating from your Hard Drive > Users > [User Name] > Applications.
Empty the Trash, then restart your Mac and download the app again.
Temporarily turn off the firewall on your Mac.
The firewall does a great job of keeping your Mac safe, but it can sometimes get in the way of installing or updating other apps. You can turn it off in the System Preferences, but you should remember to turn it on again after so your Mac is not left vulnerable. https://growrenew748.weebly.com/blog/download-spotify-songs.
Go to System Preferences > Security & Privacy > Firewall. Click the padlock and enter your administrator password to unlock the settings, then click the Turn Off Firewall button.
You should also turn off any antivirus software, as this may also be interfering with app installations.
After your app installation or update is complete, remember to turn your firewall and antivirus software on again.
Restore your Mac to its factory settings.
This is something of a nuclear option, but it’s there if you want it.
If, after all the other steps listed above, you still can’t get your Mac to install or update apps, a complete factory restore may offer the solution. Doing so will erase all your data and reinstall the macOS, so ensure you have a backup first.
You should also be aware that the entire process can take quite a long time, upwards of six hours depending on your internet speed and how much data you have.
Problems with updating your apps
Recently, Mac users have experienced a new problem in the latest version of macOS Mojave. In this problem, users can’t update their stock apps such as Keynote or Pages. They need to click an accept button in their account, but that accept button doesn’t exist!
I just checked and currently have the 9-12 package, version 8.681.0.0, downloaded 3/2/2010, so apparently the last install was in March this year, no earlier. I'd get a blue screen with the error message 'ATI2DVAG', which of course indicates the video card drivers. Hauppauge hd pvr capture software mac. I'm recording a football game this weekend to try it out on.
This doesn’t happen to everyone: some users can find the accept button without any problems. But if yours is missing, you can still update the app by deleting it from your Mac and downloading a fresh copy from the App Store.
The easiest way to delete an app is to move it to the Trash from the Application folder in Finder. Then it might be worth restarting your Mac before you download the app from the App Store again. And once you do, you’ll have the recently-updated version of it.

It seems the solution is to disable Gatekeeper temporarily while you install the new app. We strongly advise you to turn it on again afterward. You can do this by going to System Preferences > Security & Privacy, click to padlock and enter your administrator password to unlock it. Under Allow apps downloaded from: select Anywhere.
If there is no Anywhere option, open Terminal and enter the following command line:
