OK, have a little crisis here, long story: I Was running dual boot Mac OSX Mojave/Ubuntu 18.04 with rEFInd bootloader using a late 2014 intel iMac 5K. Everything working fine for a while until I got a folder called "Snap" on the Ubuntu desktop. After that I was locked out of all my user folders. Tried a few commands (recommended in this forum) in Terminal to remove "Snap" folder, but did not get any access to my user folders even after "Snap" was removed. Repaired Ubuntu by booting USB-stick from rEFInd and Ubuntu started after re-boot, then everything went wrong. The rEFInd bootloader disappeared and Ubuntu booted only, no means of choice between OS. I tried to install rEFInd again, but got a load of gibberish in Terminal and something about rEFInd not being installed properly (I am not much of a Terminal guy). Also, Ubuntu did not find/configure WiFi so I had to use wired network to get updates - which did not resolve any of the problems. Then, to enable booting into Mac OSX, I used terminal to change boot order and was able to boot into OSX. Now I have OSX booted and being locked out of any means to get into any recovery menu what-so-ever (OSX or Ubuntu). Tried OSX key commands "Cmd-R" and "Cmd/Option-R" but get a Firmware padlock wanting password and not responding. Tried holding "esc" key when re-booting but end up at the same padlock. I have tried to re-boot OSX by re-starting with RAM sticks out, holding Cmd/Option R-P but only get a repeated beeping and not the OSX boot noise - Ending up with the same padlock after inserting memory and re-booting holding in "Cmd-R". To make matters worse OSX does not recognise the USB-stick with 18.04 mirror on it, so I am out of the option running Ubuntu from the USB stick and maybe save the day that way. So here I sit wondering what to do hoping somebody have a solution: Preferrably me having the blissful OSX/Ubuntu rEFInd dual boot giving me access to both on demand or at least an option where I can reach the OSX recovery menu and start all over....... Please?

I doubt if snaps were the issue. They are totally stand alone applications and do not change booting. Do not know Mac, but those that do may need details: May be best to see details, use ppa version with your live installer or any working install, not older Boot-Repair ISO: Please copy & paste link to the Boot-info summary report ( do not post report), the auto fix sometimes can create more issues. help.ubuntu.com/community/Boot-Repair
