macOS 10.15 Catalina is Now Available on the Mac App Store

I wonder what this Supplemental Update (19A602) really changes, as it took my computer about 23 minutes to update... Only 7 minutes shorter than upgrading to Catalina.

Click where it says Version 10.15.

Thanks! So simple. Looked for more complex reason.

Updated directly from App Store for Supplemental update to 10.15 (19A602). No problems with update

Upgraded to Catalina 10.15 (19A583) without any issues. All programs I use (iMessage, iCloud, Internal Speakers) worked after upgrade.
Just installed Supplemental update. Only issue was that on the 3rd restart it defaulted to Recovery and required manual selection to Catalina. Again no other issues.

Yes, I can share my config. Altough, right now I'm on a train. I'll do it as soon as I get home. So, I'll get back to you on that.

The reason I use a iMac15,1 definition is that iMac15,1 could be configured with exactly the same processor that I have. (i7-4790k). See here, for example. https://everymac.com/systems/apple/...-inch-aluminum-retina-5k-late-2014-specs.html

I'm not sure if it makes any practical reason though.

ah, I see. you got a better match than me. cool. What audio device are you using ? ALC1150 and do you use AppleALC.kext ?

Everything worked fine for me without any problem... i7 3gen with Biostar TZ77XE4 Biostar MotherBoard

I have a Hcman LED keyboard, the caps LED worked fine in Mojave, doesn't work in Catalina

Maybe the driver app is 32 bit, Catalina requires 64 bit software - Check with the manufacturer for driver update.
