Regarding the access right, you need to be super user to create this file.Īfter a restart you should be able to see the correct resolution (2560x1080) in SwitchResX. Hi guys, need a little help here, appreciate if you guys could help. My 13" MacBook Pro mid 2014 display broke down weeks ago, I ordered a Dell U2720Q with a native resolution of 3840 x 2160 60hz.
#Switchresx sierra mac os
I am running Mac OS 10.15.4, connected my mbp to the display using mini dp to dp in attempt to get 60hz display. However, I was so disappointed when I could only run 720p 59.5hz while the other options only work at 29.5hz and below.Ĥk 60hz is not what I wanted, I only want to run 2560 x 1440 60hz or 2304 x 1296 60hz and yet my mbp doesn't allow this to happen. However, my friend's 2015 mbp can run easily 4k 60hz with my setup. I tried this patch file ( ), disable SIP, install SwitchResX and yet it doesn't work. I am very lost and almost give up.Ĭould anyone tell me if it will ever work? if it is not, I will just stop trying.Īlso, please let me know if I need to disable (reverse) this attached patch code if I do not need to use it anymore. Thought I should share in case anyone has the same issue I did. I was using SwitchResX to display 2560 x 1080 on High Sierra without issue. When I upgraded to Catalina SwitchResX no longer worked and I received the "Not activated - invalid?" message.
I tried all of the solutions above: uninstall and reinstall as a new user, update using EDID, renaming the relocated items file, etc. I reached out to the developer and he helped me troubleshoot but was ultimately told that the video drivers in Catalina had a restriction that was not in the previous OS and there was nothing that could be done, my machine just could no longer support 2560 x 1080.
