Al-kabor eqmac emulator

[Nads]

I'm getting this error when I try and use the Launcher:

Last login: Fri Jun 13 20:55:00 on ttys000
USERNAME-MacBook-Pro:~ USERNAME$ /Users/USERNAME/Desktop/EverQuestLaunch ; exit;
/Users/USERNAME/Desktop/EverQuestLaunch: line 3: ./EverQuest: Permission denied
logout

[Process completed]

Now, I see there is this fix in the connection guide, but can anybody eli5?

My advice, copy your Everwquest to a fat32 formatted USB something or other as a backup straight from where it installed on AK.
Go to a windows machine if you can but you can try this on OSX:
copy the eqhosts.txt out of the USB you just made into the top level of the USB outside of the Everquest folder.
Then edit the copy with our loginserver info. Now after this copy the USB Everquest into you computer in the path specified earlier.
Now copy the eqhosts copy you made into that Everquest you just copied over to your OSX drive.
Applications/Everquest.app/Contents/Resources.

or

Copy your exiting Everquest from your OSX to a USB as a backup, and download the attachment in the eqhost.exe thread directly to your Everquest.app/Contents/Resources WITHOUT modifying it or it will get corrupted.
