mac os Catalina on macbook pro 2015

Until macOS Catalina is released in the Mac App Store, we cannot discuss it as a beta product in the Apple Support Communties. Once released, there will be a Catalina community made available here, and at that time, repost your question.

Yes, you can go back if you format your hard drive and install Mojave via a bootable USB drive. Please let me know if you tried Catalina as I have a 2015 Macbook Pro 13'' that runs Mojave and I am curious to know whether it worths upgrading.

Thanks!

Don't upgrade. I also have a 2015 Macbook Pro 13''. I have ton of issue upgrading to Catalina. Freezing/crashing of a ton of Electron Apps, Virtual Memory/dynamic paging issue causing heavy performance lag, safari crash on a lot of websites which worked fine in Mojave on lower spec machine, 32bits app support ditched, legacy safari extensions ditched. I deeply regret updating. It offer nothing more than Mojave ; worse, it offer less. Once I'm done with my current School assignment, I reinstall fresh Mojave.

Just updated to Catalina on a Macbook Pro Retina 15" mid -2015 i7 with 16GB RAM, my system keeps crashing after about 3 minutes of use. Really wishing there was a way to easily revert back to Mojave.

I wouldn't.

Just look around, there are way too many people with rather serious problems (which I relate to Catalina)

I too did it on my mini, and went back to Mojave, which in itself (downgrading to Mojave) was quite an odyssey.

OTOH, I run Catalina on my Air, and there all is working perfectly. The only thing was that the security-update (10.15.2) had to be downloaded/installed manually, but that's not really an issue and will be solved one day or another.

I upgraded to Catalina not too long ago from Mojave on a:

MacBook Pro (Retina, 13-inch, Early 2015)

2.7 GHz Dual-Core Intel Core i5

Memory 8Gb 1667 MHz DDR3

Graphics Intel Iris Graphics 6100 1536 MB

Animations are NOT smooth as before. System seems sluggish. System does not crash as others have reported.

I have a Retina, 15 inch mid 2015 McBook pro with macOS high Sierra 10.13.06, and Macintosh SSD. I get errors trying to upgrade to macOS Catalina. The SSD is almost empty but I got the error the volume requirements are not met! Then I got the error that the SSD is encrypted! I tried to decrypt it, and the got the error that the SSD is decrypted so macOS Catalina cannot be installed. and now, I got the error that macOS Catalina cannot be installed on Macintosh SSD. So, I am confused! I already got the Apple Genius Bar to inspect the laptop, they assured me that the hardware and software are fine and there is no problem. I appreciate your help.

Don't do it! Long list of problems, totally regret updating!

Updated today on a late 2013 iMac and no issues

Do not upgrade to catalina, It's really slow -. Better to use to mojave !!

I am wondering if I should upgrade. It's available now so no reason not to discuss it for anyone!

What are the worst problems when you upgrade?

Can you go BACK to mojave if you don't like catalina?

Thanks
