Intel Mac + Catalina = no clamshell
Hi all,
With the legacy drivers I don't get a signal on my single external monitor. With the DL Manager 1.3, I can get my second screen up but if I attempt clamshell mode, the screen will lock every 10-15 seconds. I've seen plenty of issues for this on the M.1 macs with Big Sur but I can't find any info on the older intel MBPs. (Also, strangely I need to 'extend' to my second monitor instead of duplicate because on logins/reboots, my mouse stops moving after it's crossed 1/3rd of my screen. It stops as if it's reached the side of the monitor, but I can see it clearly hasn't.) |

Solved
Solved my 5.2.5 issue (and now able to do everything I want w/ clamshell working!)
Fully uninstall 5.2.5 Turn laptop off (Then I had to disable csrutil and delete the old kext which would never delete during the uninstall: ) Boot to recovery, open terminal, csrutil disable Reboot again Navigate to: Macintosh HD\Library\StagedExtensions\Library\Extensions\ Delete "DisplaylinkDriver.kext" Install 5.2.5 Reboot normally Enable Screen recording (Then you'll probably want to renable csrutil: ) Reboot to recovery again Terminal: csrutil enable The hidden one in there of course is deleting the bad kext which can't be done without disabling csrutil |
