So I have been a Windows user all my life (more than 20 years), I finally got fed up of Microsoft's bugs, updates, telemetry, etc. and decided enough was enough. I have no more time to keep formatting daily and wasting my precious time, it's time for a change.

I went ahead and sold my Alienware Area-51m and bought the latest MacBook Pro 15 2019 model fully specced out with the i9-9980HK and Vega 20 Pro.

As I was awaiting for my laptop to arrive and reading these forums seeing how many problems people are experiencing from upgrading, I decided to clean install Catalina the moment I received the laptop, didn't even see what Mojave feels like so my first experience with macOS was with Catalina.

I installed it just fine, logged in with my iCloud, everything was syncing properly from my iPhone including Mail, Notes, Photos, etc. thanks to the supplemental update which fixed those syncing bugs.

I installed all the apps that I purchased but then I realized, when I reboot, sometimes the loading bar would reach 70% then the screen would go black so I had to force shut down maybe 3 or 5 times until I would finally boot.

I formatted my laptop more than 5 times trying to figure out maybe what app that I am installing perhaps is causing this but no luck.

I contacted Apple Support and they made me reset my NVRAM and a few more things to no avail. They said I need to bring it in to the Apple Store but the appointment was only after 1 week.

I was frustrated as I spent an arm and a leg on this laptop. I didn't want to believe there was a hardware issue as when I am booted the laptop could run forever with 0 issues it's only the rebooting that was the problem.

Did a lot of research and tried a few things like disabling automatic graphics switching in the power settings, trying to enter my password and hitting enter while at that black screen, nothing worked.

Finally by accident I discovered that if I set the scaling back to default, the issue doesn't happen, it's only when I change the scaling to anything other than default it happens but I was not happy as the default scaling is not so sharp and clear I want a scaling of 1440x900 which looks super sharp and crisp. But I had to live with the crappy default scaling until maybe one day Apple would fix this, I did send them feedback regarding this issue on their site by the way.

Another thing I didn't like was, I didn't feel the laptop as snappy as I anticipated with the specs that I got. I thought that's just how macOS is.

Today, finally, I thought of formatting and downgrading back to Mojave which the laptop originally shipped with, first thing I did was change the DPI scaling to 1440x900 and rebooted and BAAM! It rebooted just fine! Tried a few times, it rebooted just fine every time! I am so happy!

Also, Mojave seems to me way snappier than Catalina, in Catalina I felt there was a bit of a lag in everything I did including minimizing/opening Windows, opening apps, it just felt weird. Now with Mojave everything is much faster.

So glad I did this downgrade and I can finally enjoy my laptop the way I wanted. I am not sure I wanna take the risk of upgrading to Catalina again even when the next update hits. It seems like I am the only one with this issue since I have the Vega 20 Pro others I've asked on the forum who only have the Intel HD Graphics didn't have any boot issues when they changed the DPI scaling.

i upgraded to catalina, best thing i ever did! everything works well (or, pretty well... a few kinks). but my work apps are happy, and my imac especially is doing really well.

seems we are not all having the same experience; makes sense, considering the hardware, the apps we use... there are lots of variables. so, no 'one size fits all'; for some, moving forward works, for others... moving backwards. and, either way, if we can work, and are happy... that's the most important thing of all.

Does your laptop have a dedicated graphics card like me? If it doesn't, then perhaps that's why you're not getting the issue that I'm facing

It seems to be the Vega graphics cards. I do not know why Apple chose to ignore the most top spec GPUs but these seem to be the root of all these startup/kernel panic issues. I have an i9 iMac Vega 48 and get 4+ kernel panics a day when I take my 15 minute breaks.

Honestly, I am surprised there are this many problems especially with the new Mac Pro around the corner. If Apple messes up with bad software on a $6,000+ new Mac Pro, that will be the end of the Mac Pro line. How did Apple mess up this badly?!

Surprises the crap out of me too. I bought the best of the best and I expected the best, this little boot bug drove me nuts for days, endless amounts of formatting and trial and errors, installing one app at a time and rebooting, I couldn't ever expect that such a small setting would almost brick the laptop. The Apple Tech support were almost certain it was a hardware issue that needs to be fixed and to make things worse, the first available appointment was in 7 days so I had to sit and use this *broken* laptop that I paid $7200 USD for another 7 days and God knows how long it would take for them to fix it.


They would have probably formatted it and told me "sir, your laptop is fine you can take it" since they wouldn't change the DPI scaling like I did.

I just called Apple Support in Dubai and told them about this whole issue. The tech support agent told me to expect a new update for Catalina very soon.
