Hi – I have been having some issues on my late 2013 Imac since upgrading to Catalina. A lot of library messages in the logs for example. Sometimes if I go to shutdown I get a black screen for a while then it reboots, other times it’s fine. Sometimes when emptying the bin it just sits there on the screen and other odd behaviours. Have run Malwarebytes and nothing untoward there.
First I clean (erased) the Hard Drive (actually internal ssd). Then tried to do the 'reinstall'. Since the HD was completely. Wiped, I had to do an Internet reinstall. I was stopped in my tracks with the message 'Can't download the additional. Components needed to install Mac OS X'. Some people had trouble with Internet connections in this.
Macos Reinstall Catalina Update
- The key to reinstall mac OS Big Sur, Catalina or Mojave without losing data is the backup, since no one can guarantee all data will be perfectly maintained after macOS reinstallation. However, if we unfortunately lost files after macOS reinstallation, Time Machine or Cisdem Data Recovery is helpful to recover them back.
- I can see the answers suggested here on how to accomplish that: Mac stuck in restart cycle after failed macOS Catalina update However, when trying to recover / reinstall macOS - the installer also tells me - you don’t have enough free space to reinstall macOS.
- Reinstall the version of macOS stored on your computer’s built-in recovery volume: Press and hold Command-R. In the Recovery app window, select Reinstall macOS Big Sur, then click Continue. Follow the onscreen instructions. In the pane where you select a volume, select your current macOS volume (in most cases, it’s the only one available).
Reinstall Macos Catalina Not Working
It’s got very frustrating so I thought I might try and download Catalina again and refresh it. Using the Recovery, Installed OS option, does this download a new copy of the OS to the Macintosh HD partition while keeping Macintosh HD-Data partition separate? I have a Time Machine backup and also other separate copies of the three users Photos library from the iMac but wanted to know if I can re-install the OS without specifically doing anything else to keep my data. Sorry if this is basic question but in Mac terms I am not that experienced.
