I have been using FirstEdge V4 since 2009. My son recently upgraded my Mac to macOS Monterey Version 12.6.2 and now I am unable to open FirstEdge as it says it needs to be upgraded. I have had to log on to the comunity forum also using my work email address as it does not recognise my personal email address which is what I registered with in 2009.
I have tried to download it again but I cannot open it as it comes up with the following:
"MYOB FirstEdge V4 cannot be opened because it is from an unidentified developer."
Thank you for the post and I'm happy to assist you with this. The reason why you cannot access your FirstEdge V4, because it's not compatible to the newer versions of macOS. For you to access it, you need to roll back the version of your macOS or cross grade your file to MYOB business platform.
Please let me know if you need further help.
