Jan 29, 2012 Hello all, I have a MacBook Pro running OSX 10.6.8. I am trying to install a new game that I recently purchased. When I insert the disk, nothing happens automatically. So when I go to the finder window and click on the 'install' part of the game disk, I get a dialog box that says 'This. Nov 24, 2017 Open User Accounts. Click the link that says 'Change User Account settings'. Move the slider from the top position to the second position where it will say 'Don't notify me when I make changes to Windows settings' Alternatively, when you install your software, right click the setup button and say 'Run as Administrator'.

I have been trying to get a software CD to open to install on my new computer with Windows 10. After many hours I have to say I HATE WINDOWS 10!!!!! In actuality, the clean install was performed, the Mac is just booting from the wrong startup device. The fix is to open the Startup Disk preference pane and set the startup disk correctly for your Mac. Reset NVRAM and SMC: The NVRAM and SMC hold information used by your Mac during startup.
macOS Recovery makes it easy to reinstall the Mac operating system, even if you need to erase your startup disk first. All you need is a connection to the Internet. If a wireless network is available, you can choose it from the Wi-Fi menu , which is also available in macOS Recovery.
1. Start up from macOS Recovery
To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following sets of keys on your keyboard. Release the keys when you see an Apple logo, spinning globe, or other startup screen.
Command (⌘)-R
Reinstall the latest macOS that was installed on your Mac (recommended).
Option-⌘-R
Upgrade to the latest macOS that is compatible with your Mac.
Shift-Option-⌘-R
Reinstall the macOS that came with your Mac, or the closest version still available.
You might be prompted to enter a password, such as a firmware password or the password of a user who is an administrator of this Mac. Enter the requested password to continue.
When you see the utilities window, you have started up from macOS Recovery.
2. Decide whether to erase (format) your disk
You probably don't need to erase, unless you're selling, trading in or giving away your Mac, or you have an issue that requires you to erase. If you need to erase before installing macOS, select Disk Utility from the Utilities window, then click Continue. Learn more about when and how to erase.
3. Install macOS
When you're ready to reinstall macOS, choose Reinstall macOS from the Utilities window. Then click Continue and follow the onscreen instructions. You will be asked to choose a disk on which to install.
- If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
- If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
- If the installer is for a different version of macOS than you expected, learn about macOS Recovery exceptions.
- If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
Please allow installation to complete without putting your Mac to sleep or closing its lid. During installation, your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
If your Mac restarts to a setup assistant, but you're selling, trading in, or giving away your Mac, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
Mac Won't Update
macOS Recovery exceptions
The version of macOS offered by macOS Recovery might vary in some cases:
- If macOS Sierra 10.12.4 or later has never been installed on this Mac, Option-Command-R installs the macOS that came with your Mac, or the closest version still available. And Shift-Option-Command-R isn't available.
- If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might offer only the macOS that came with your Mac, or the closest version still available. You can upgrade to a later version afterward.
- If your Mac has the Apple T2 Security Chip and you never installed a macOS update, Option-Command-R installs the latest macOS that was installed on your Mac.
- If you just had your Mac logic board replaced during a repair, macOS Recovery might offer only the latest macOS that is compatible with your Mac.
If you can't get macOS Recovery to offer the installer you want, you might be able to use one of the other ways to install macOS.
Other ways to install macOS

- You can also install macOS from the App Store or Software Update preferences. If you can't install macOS Catalina, you might be able to install an earlier macOS, such as macOS Mojave, High Sierra, Sierra, El Capitan, or Yosemite.
- Or create a bootable installer disk, then use that disk to install macOS on your Mac or another Mac.
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.

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.
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.
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.
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. https://generousga148.weebly.com/twitch-streaming-software-for-mac-free.html.
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!
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.
How to fix app problems in macOS Catalina
What to do if you can’t approve new apps in macOS Catalina
Another beta problem in macOS Catalina is the inability to approve new apps from the Security & Privacy System Preferences. We explained one way to do this above, but lots of users running the beta version of macOS Catalina have found it doesn’t work.
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: Green screen software mac 2016 free.
Restart System Preferences and you should see the Anywhere option. You can undo this at any time using the command line:
Make sure you enable Gatekeeper again after installing your app, or you will leave your Mac vulnerable to attack! App to download youtube videos on macbook pro.
What to do if you can’t update or sign in to the Mac App Store
If you’ve been test-driving macOS Catalina through Apple’s Beta Software Program, you might have experienced problems using the App Store on your Mac. Lot’s of users are unable to update or download new apps because the App Store doesn’t let them log in.
Despite entering the correct Apple ID username and password, the Mac App Store still appears as though they aren’t logged in. If this has happened to you, try the following user suggestions to resolve it:
- Sign out of your Apple ID from System Preferences > Apple Account.
- Sign out of Apple Music by going to Account > Sign Out from the menu bar.
- Try downloading the apps or updates from a different user account.
- Update macOS Catalina to the latest beta version, or revert to a stable public release of macOS Mojave.
