I need help with my Sapphire RX580 8GB. It works and I have it connected to a BenQ EW3270U (4k monitor through DP), but I noticed that the quality of my video is not exactly great; I just don't feel like it's up to spec with some fuzziness and everything just isn't as sharp as I expect it to be. It's hard to explain exactly what I see, but especially when there's transparency in windows for instance, I see what I would compare to colour compression artifacting in the gradients of the images showing through the transparency effects. It looks like a video with fading on Youtube but the compression makes it look like waves of pixels as opposed to a real gradient, if that makes any sense? It's impossible to film or photograph properly, and - the part that gets me - if I do a screenshot, it's not visible! I must have been super tired when I posted... it's visible on screen shots after all (see attached). It screams graphic acceleration issues to me but I really am at a loss on how to diagnose this issue further. It's not unusable or anything, but I want to get it to work properly and get as much as I can out of it all.
As a comparative I did plug in a Retina MBP to the monitor to make sure it wasn't the issue and as expected, I did not see any of this with the MBP.
I have Lilu and WEG in my 10.14 kext folder, and my (shameful) config is attached, but I more than likely am missing something important...
All this explained, I want to point out a few things: this is an old machine (built 2012) and I had the same config throughout with exactly 0 issues. This is one reason why I not only never had to optimize it, but I now also pretty much fell off the Hackintosh bandwagon: I am not exactly well versed in all the technical backend of this community as I was until now lucky with a plug and play machine with no issues.
I will need a lot of help to get back up to date... that said I also had incomprehensible and undiagnosed issues getting the RX580 to work on this machine. Even if it was effortless for everyone else, I had to do a LOT of troubleshooting and in the end, I have no clue how I got it to work! So I'm mortified of changing anything on it without getting some advice first since everything, iCloud and iMessage included, works. I'll be happy to fill in any info and I'm hungry to learn. It's just a bit daunting to start over and my searches have discouraged me a but. I know beggars can't be choosers but I have a 60-hour a week job and I just need a bit of guidance if anyone wants to help me off my training wheels I fully know I'm in a bad spot and quite frankly I'm ashamed of it. Help me make it better please.

when attempting install 10.10 to my old PC, it reboots everytime when attached pic shows up. my hardware is:
mb - unika p35 (with ich9) 775pin
cpu - intel xeon x3210
video card - nv geforce 8600gt
could anybody know what was wrong? or is it possibly because of the video card, or the powermanagement?
Clover limits the number of gpus to 4 :
from Clover source code : rEFIt_UEFI/Platform/Settings.c :
GFX_PROPERTIES gGraphics; //no more then 4 graphics cards
Anybody knows why?
This number is limiting for me :
- 1x gpu is AMD display GPU
- 1x gpu is Supermicro's built-in vga IKVM output (Matrox 0x532102B)
- 3x gpus Nvidia for Cuda
I At present, I have to take off one Nvidia (but I'm trying to disable the build-in vga IKVM output through software, so that it's available for other operating systems : I'll make another post on that topic, to keep things clean)
I’m starting a designing course and I’ve been told a Macbook is the best option to handle specific softwares like adobe Photoshop perfectly.
Right now, i’m studying in Lisbon, Portugal. So, I would need to buy it from some Portuguese store, in case I need to claim warranty.
Anyway, I started my search and found som results, fort some Portuguese stores , i’ll leave a link below.
I'm aware that a desktops like a Mac Pro would be a much suitable solution, but I need a laptop to take to classes.
I think a 13” Model is enough since the retina screen helps me see details better, but I don’t understand the software requirements for each type of software.
What do you guys think I sould buy?
Feel free to make any question or suggestion!
