For developers, on the other hand, this secondary screen can be used as a drawing tablet using supported apps. For ordinary users, this means getting a secondary display for free. Another major feature is Sidecar, which can turn your iPad into another display. First revealed during the WWDC 2019 conference in San Jose, California, macOS Catalina introduces some new exciting features and functionalities.Īs we say goodbye to iTunes, macOS Catalina brings in new apps and features to the table, including Apple Music, Podcasts Books, and TV. If you have any questions, feel free to ask.Apple’s latest macOS, Catalina, has just been released to the public last Octoand you can now install it on your Mac, as long as your device meets the hardware requirements. The syntax to delete is: tmutil deletelocalsnapshots Īfter deleting them, run again the first command, just to be sure there will be no results.Ĭatalina will boot fast and you will be able to login and use it normally. In my case I had 7 local snapshots as seen above, and we must delete them to fix Catalina (I decided to delete them all, because I have my backups already on my always connected external disk used by Time Machine) Type the command below to list all local snapshots Once on the terminal window prompt, lets check if this is the cause: But it is not frozen, it is analysing data on disk. What technically happens when the progressbar stucks on 90% forever is that the system is somehow verifying those local snapshots, and it take hours, so we thing the system is frozen there just before the login screen appears. I have an external disk that always worked well, and it was working very well today on Catalina.īut Catalina creates various local snapshots also on the root disk (and there is no way to disable localsnapshots like on previous MacOS versions which was possible to disable just the localsnaps) Local snapshots are backups created on the local disk, even if you have an external disk connected and dedicated to time machine. The problem was caused by time machine "local snapshots". I dedicated about 2 hours investigating it and I found the cause and how to solve it. Rebooting was working perfectly since installed, but after about 6 hours using the system I rebooted it again and my system behavior was exactly like yours. I just had the same issue after rebooting Catalina, the bar at approximately 90% for a long time, never reaching the login screen. Does anybody have any idea how I can resolve this? I was able to reboot into Safe Mode, where I deleted all my LaunchAgents and LaunchDaemons. I have tried moving out of the WiFi area to see if that would help but it didn't. Kextd stall, (60s): `GFX0`, `IGPU`, `GPUC`, `IOResources`ĬonsiderRebuildOfPrelinkedKernel triggered rebuild Interface link is not up, do not pull packets yet Notice - new kext, v15.0.3 matches prelinked kext but can't determine if executables are the same (no UUIDs). I hard rebooted the machine and booted into verbose mode (CMD+V) to see the output. The bar got to approximately 90% complete and would not continue. The machine installed on the black screen with the Apple logo no problem, then rebooted to the login screen where a progress bar was then shown. Catalina hung for over an hour when finishing the install.
