![]() ![]() Next the normal loading icon will spin, then the progress bar for the SafeBoot load up appears at the bottom. HOLD SHIFT UNTIL you see the apple icon and hold it for a second after and release. I am still trying to figure out how to permanently delete all of the files from my mac.īoot up into, SafeBoot by doing the following command keys after hitting the power button. Before i go further though i would like to say SwitchResX is a totally insecure and unreliable pece of software. I would like to tell you this method is 100% guaranteed to work and the files are always replaced and if the problem is somehow again created then do the following steps. So as you all might know is that i too have had this problem hence me posting here. Or maybe there is I noticed some scripting junk that came with it, I'll have to look closer at that. Good luck, it's really annoying that there's no easy kill for switchresx from the command line included in it. For setting screen sharing to be enabled from the command line. Or you could boot into single user mode (google it, it's not hard to find). If you don't have screen sharing enabled on the mac with the bad display caused by switchresx, then you can enable it via ssh and the command line (you do have ssh enabled, right?.). The solution: use the screen sharing app from another mac and turn off and uninstall switchresx on the affected mac. Resetting pram gave me a grey screen with some weird ghosted vertical lines of a lighter grey with the spinning thing and the apple, then back to the colored bars a few seconds later. Resetting pram didn't work, it just would display the messed up screen right at power-on (not black in my case, but vertical stripes of a few bright colors). I just had the dead screen issue with switchresx as well. You should remove this file, if you can access the file system, either byġ) accessing the file system from an other Mac on the network, from ssh or by mounting a shared folders.Ģ) OR starting up in single user mode (or safe mode)ģ) OR at last resort: reinstalling the OS above the existing install, which will keep your existing profiles, but remove the system modified files. This file is located in /System/Library/Displays/Overrides/ and is the last modified file, that you can find if you sort by date. This will delete all changes that you have made for this monitor.Īs a last resort, if you can't even start SwitchResX itself, you'll have to delete the monitor profile that you modified when you created a new custom resolution. If nothing above works, try to press the "reset" or "factory defaults" button in SwitchResX Control for your monitor. You can remove this file to get back the standard resolution in your user account. If this solves the problem during the reboot, but not in your user account, a similar file named ".plist" exists in your own /Users/yourname/Library/Preferences/ByHost folder. The file named Library/Preferences/ contains the resolution that the System tries to use at startup. Release the shift key when you see the "spinning gear" on the startup screen. When you hear the startup tone, hold down the shift key. To do that, turn your system off, then restart. Is my monitor destroyed ? How can I go back to the light ?Ī: First, try to reboot in safe mode. Q: I've defined a new resolution and rebooted, and the system boots with a black screen. This will Shutdown, -Restart type down, at time Now. This ought to fill in the rest of the line with the filename, if it doesn't, post here and I'll update the instructions accordingly We want to delete the ".plist" file, where the Xs represent your computer's hardware MAC address.Ħ) Type "rm /Users/>/Library/Preferences/ByHost/"> If there's only one other one there, well, that makes it easy. ![]() Choose the one that belongs to your account. You'll see "Shared" and some number of other users. This will Mount, -Write access, -Update the already mounted filesystem /ĥ) Figure out your short user name by typing "ls /Users/" you'll need it in the next step. Now that we've determined the hard drive is clean, let's mount it read/write (However, because you don't have a disk problem, this is most likely just a formality before you can mount your hard drive) If it doesn't say your hard drive is OK, then run the command again until it does. This will run a File System ChecK, -Force run, -answer Yes to all questionsģ) That should report back something like "Macintosh HD is OK!" or whatever. To change this.Ģ) Type "/sbin/fsck -fy" (without the quotes) You'll see a whole bunch of text fly byīy default, your hard drive is mounted as read-only. This would help with a disk problem, but not with an improperly configured display problem.
