- Mac Won't Install Software Update
- Mac Software Update Couldn't Be Completed Mac Error Message Version
Jun 22, 2018 If you are experiencing this issue with your update, here are a few tips that you can use to address this issue. Before proceeding with the steps below, we suggest that you ensure your Mac’s clock is correct. If your Mac’s Date&Time do not match your current timezone or date, macOS often won’t install. Go to System Preferences Date & Time. Apr 15, 2020 And, if you haven't installed the macOS yet, make sure you visit our how to download and install macOS Catalina guide for the step-by-step process of getting the new software on your Mac. Feb 05, 2016 Bumping an old thread as well; I'm getting the same issue on my Mac Pro 1,1. It happens on both accounts, so it's not a login item issue, I don't run any firewall or AV, so it's on Apple right now. Been this way for at least 2 weeks, hopefully gets resolved.
Try these steps first
- On a Mac with macOS Catalina 10.15, make sure your Mac is up to date. If you have a Mac with macOS Mojave 10.14 or earlier, or a PC, make sure you have the latest version of iTunes.
- If your device couldn't be restored and you get a message that 'an unknown error occurred [error number],' use these steps.
Feb 08, 2019 Last Wednesday he installed an update of macOS. Yesterday morning during startup he got the message 'MacOS Installation Could not be completed' Then he restarted the iMac several times. The above message came back every time. Then he turned off the iMac. After turning on the iMac, he pressed the CMD + R key and chose 'Reinstall macOS'. Safe mode startup succeeded but the next time the (normal) boot ended as before, with the infamous “couldn’t complete” message. I followed Luis’ hint then. Actually on my High Sierra macbook it was clicking “apple logo - startup disk” and then just confirming already.

If you see error 10, your iOS device might have a newer version of iOS than is supported by your computer. You'll need to update the software on your Mac or iTunes on Windows before you can update or restore your iOS device.
macOS 10.11 and later:
- Disconnect and then reconnect your iOS device to your computer. You might need to unlock your iOS device before it is recognized by your Mac.
- When you see a 'Software update is required to connect to your iOS device,' click Install to download and install the software so your Mac can update or restore your iOS device.
Windows: Update to latest version of iTunes.
If you continue to see error 10, or you don't see a dialog asking you to update the software on your mac, contact Apple Support.
