First launching issue... HELP!
Hello,
To the best of my knowledge this particular forum is no longer being monitored by staff. Not being familiar with the problem you are experiencing myself I can only suggest that you submit a suport ticket here:
support.guildwars2.com
’Ask A Question’ option in the middle of the top of the page.
You might also consider running a disk repair and permissions repair using Disk Utility located in your Macs application folder and located in the utilities folder subfolder.
I would recommend that any time you experience a problem with the GW2 Mac client that you submit a ticket to keep development updated on issues that are occurring.
I hope you get it working soon.

As a thought, it seems you are running at bare minimum specs also. But I’ve seen lesser systems run, just not perfectly.
If you wish to go for the ticket first, go right ahead, check the sticky first. Please come back here and post whatever solution worked for you. But you may wish to try a couple options I’ll list as well. An smc or pram reset may also be needed.
You may also wish to try these basic Mac client troubleshooting steps also (length warning):
1.) run software update to ensure all drivers and os are up to date.
2.) try repairing disk permissions via Disk Utility first. Then…
3.) repair the client install
Open Terminal
Type the following:
/applications/guild\ wars\ 2.app/contents/MacOS/cider —use-dos-cwd C:Gw2 -- C:\\GW2\\GW2.exe -repair
You can copy and paste that in, but (check the dash) you must change the dash before the word USE or this will fail the forum shows an em dash (—), but it is supposed to be 2 consecutive en dashes (-). Run it and let it go until finished. FYI if you type the command yourself or paste it, they are 2 dashes (-) side by side… I’m noticing one sometimes looks like an em dash… It’s 2 en dashes though. (the dash before USE is 2 regular dashes)… Reiterated due to previous confusion about that dash on these forums.
4.)Perhaps after doing that, if it doesn’t work, you can try to delete the contents of the gw2 data folder, it’s a pain to get to the right one: this step is a general fix for many t kitten ues, even without the previous steps
Mine is located under the hidden Library folder (navigate using finder, do not use spotlight to search)
/[yourharddrivename]/users/[yourusername]/library/application support/guild wars 2
You may want to copy/paste this folder to your desktop as a temporary back up, just in case.
Delete the contents of that specific folder (you should see files like this contained within “config, dyndata.dat, user.reg, userdef.reg, and folders p_drive and wineserver…namestuff…loca..[long name]” just to list a few), then re-run the client..
~~Your folder is probably hidden (as is the default). Hidden folders display as greyed out text and icons. I found this after googling:
http://m.wikihow.com/See-Hidden-Folders-on-Mac-OS-X-and-Other-Recent-Models
Others claim alt+clicking a file/folder unhides the contents, but that was never successful for me. At least the link has visuals for you. Hope it helps.
5.) If none of this works, check the sticky and submit a ticket, then please come back here and report the fix that worked for you.
Good luck and let us know.
