My Experience Performing
In-Place Upgrade of Mojave 10.14.6 to Catalina 10.15
In-Place Upgrade of Mojave 10.14.6 to Catalina 10.15
Updates:
- 13 October 2019: Before upgrading from Mojave to Catalina, make a full bootable backup. Then install latest versions of the following kexts on the Mojave system before beginning the Catalina upgrade:
- Lilu
- WhateverGreen
- AppleALC
After performing the upgrade last night, here's a quick summary of my experience. At times I was certain that the upgrade process had crashed or frozen, but in fact it worked. Here's how it went...
- My SMBIOS: Mac mini 8,1 (with VirtualSMC)
- Made a full bootable backup of the Mojave SSD.
- Because my home or user folder is on a different SSD, I made the following backups of that drive:
- Time Machine.
- Acronis Backup to Network Attached Storage (NAS).
- Began the Catalina upgrade from System Preferences --> Software Update.
- This was an approximately 8.09 GB download.
- Catalina installer opened a window in Mojave and began the preparation work.
- When ready, it asked for a reboot.
- The real install begins after the reboot.
- When machine rebooted, there were new boot volumes at the Clover Boot Menu.
- Selected Boot macOS Install from Mojave
- The standard black screen with a single Apple logo appeared, along with standard boot progress bar.
- A little past the midway point those short purple horizontal lines appeared.
- These lines are a symptom of GPU VRAM testing. Nothing to worry about.
- However, it took almost 5 full minutes before the screen finally switched to a white background and "Installing MacOS Catalina" appeared.
- I thought the system had crashed or frozen, but glad I waited.
- Phase 1 of the installation began.
- The message on screen stated:
- 25 Minutes Remaining, and then jumped directly to...
- 16 Minutes Remaining, and then after another long pause (maybe 8 minutes or so) jumped back to...
- 25 Minutes Remaining.
- During this entire phase, the progress bar was stuck at about the first letter "l" in Installing MacOS Catalina.
- It seems this first phase is analogous to the sudden-reboot first phase of Mojave.
- Anyway, the system auto-rebooted (no graceful countdown) with "25 Minutes Remaining".
- The message on screen stated:
- Back at the Clover Boot Menu, I selected once again:
- Boot macOS Install from Mojave
- Phase 2 of the installation began.
- Once again it took a good 5 minutes or more before the single Apple logo gave way to the white background and the message:
- "25 Minutes Remaining"
- And now the progress bar moved forward in a the familiar, normal manner.
- And the remaining time indicator moved normally as well.
- Finally there was the familiar graceful countdown for a final reboot.
- The keyboard and mouse were not responsive during this entire phase.
- When the countdown ended, it took another 20-30 seconds to reboot the computer automatically.
- Once again it took a good 5 minutes or more before the single Apple logo gave way to the white background and the message:
- Now back once more at the Clover Boot Menu, the Boot macOS Install from Mojave option was gone (which is, of course, the correct behavior).
- This is the indication that the setup is complete.
- I selected Boot macOS from Mojave (will rename the SSD later).
- Logged into Catalina.
- Followed a couple of welcome screens.
- And the system was up and running.
- Sound
- WiFi / Biuetooth
- Handoff / Continuity
- Sleep / Wake
- Reboot / Shutdown
- Network
- Thunderbolt
SideCar on iPad Pro 11" showed only black screen.I have Fenvi FV-T919.Will switch SMBIOS to iMac 19,1 later today or tomorrow.
- UPDATE: Sidecar is fully working now, but requires a non-T2 SMBIOS such as iMac19,1 or iMac18,3. Please see this post for details.
- When connecting an iPad, iPhone or other iOS device, it appears directly in Finder and can be managed through Finder.
- This enhances the sense of integration between macOS and iOS devices. It's a very welcome change.
- The new Music app begins by updating the iTunes library and it seems to download new artwork (album covers).
- Nice to see the former "corporate giant" called iTunes broken up into a handful of more elegant and streamlined applications.
- The new Photos app also updates the previous Photos library. This can take some time so make sure the computer doesn't sleep or reboot (as an extra precaution).
- One of the Catalina Public Betas corrupted my Photos library during the update procedure. Thankfully I had a backup.
- The new Mail app also updates the previous Mail database. This happens relatively quickly.
- There's a lot more yet to discover (much of it is under the hood), but overall first impressions are quite positive.
