Upgrade Macbook Air 13-inch early 2014 High Sierra 10.13.6 to at least MacOS 10.15 (Catalina)
Hey,
I have now spent my whole evening trying to fix my upgrade issue. My Macbook is not allowing for any MacOS upgrades at all, and different error pop-ups appear each time I try to install either Mojave or Catalina. I get either "the recovery server could not be contacted" or "downloading installer information to the target volume failed". I have tried several ways to fix this:
1) Turn off Macbook for at least 20 min, turn it back on.
2) Change the date/time preferences accordingly with each MacOS release date.
3) Checked compatibility between my current hardware/software and desired MacOS upgrade.
4) Checked that there are both memory GB and Macintosh GB available for required update.
5) Wifi is fast and stable. (But I haven't connected my Macbook directly through ethernet yet, but I doubt that is the issue since my WIFI connection is very fast and sound).
6)Followed Apple's procedure for MacOS upgrade (I have reached/found each MacOS upgrade, both Catalina and Mojave, through Safari which has then automatically made the upgrades available through the App Store)
I'm not sure what else I can do at this point. I thought the leap was to big between High Sierra and Catalina, but I can't even get the Mojave version. What can I try next?
MacBook Air 13″, macOS 10.13
