MacOS Catalina is a major update that introduces a range of new features and changes including cross-platform app support for third-party apps, no more iTunes, iPad as a second screen. 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. Install macOS Catalina. Now, you can roll back from macOS Big Sur using the bootable installer. Plug your hard drive (which is now your bootable installer) into your Mac. Open System Preferences Startup Disk. Choose your bootable installer as a startup disk and press Restart. Your Mac should start up to macOS Recovery.
Reinstall Macos Catalina Without Internet
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.
Reinstall Macos Catalina From Big Sur
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.
