pm2 dosn`t start mm.sh after reboot
- 
 @sdetweil how can I execute this script? 
- 
 @trividar read the instructions at the link I gave, 
 in a terminal window , use finder to find ‘terminal’
- 
 @sdetweil OK I found the link… bash -c "$(curl -sL https://www.dropbox.com/s/rlh710ng0zwv3vp/raspberry.sh?dl=0)"just a question, I have set up the magicmirror with all my settings etc. can I just execute this without loosing my stuff?? 
- 
 @trividar no… if u have it running, why do you need to install again? if you don’t have it running, then u need to install… you can copy the config.js to the new system, but you will have to install the modules and make sure to handle the dependencies they require 
- 
 @sdetweil because I can’t get pm2 to work on my mac mini catalina 
- 
 @trividar oh, pm2… then use the new script for that 
 see here
 https://forum.magicmirror.builders/topic/10907/new-script-to-install-fix-pm2-config-for-start-on-bootsometimes it doesn’t restart on boot like I think it should (on catalina, worked great on sierra an high sierra). haven’t found the problem yet 
- 
 @sdetweil oooh perfect… I will try it… do i see this right, I should execute it outside from MM? cd bash -c "$(curl -sL https://www.dropbox.com/s/cy2z7lbkpifcbrk/fixuppm2.sh?dl=0)"
- 
 @trividar execute anywhere, it figures it out 
- 
 @trividar thanks for asking about catalina… I have found the ‘problem’ with pm2 restart… do sudo nano /Users/$USER/Library/LaunchAgents/pm2.$USER.plistright at the top there is a string ‘UserName’ shown below 
 the space after the < is because this forum sees the < as a special formatting tag…< key>UserName< /key> < string>?????< /string>anyhow, delete those two lines 
 save the file (ctrl-o,enter), and exit, (ctrl-x)then restart (via shell), sudo shutdown -r now
- 
 @trividar I’ve added all that to the fixup script… (and the updated install script) so, if u haven’t done this manually, run then script, then restart your mac
