MonoDevelop not starting up on Mac

[Jibidiah]

MonoDevelop isn’t starting up on my Mac. I can try to open a script with it and the MonoDevelop icon shows up in the Dock and just flashes like 5 times then disappears. I tried just opening up MonoDevelop and it does the same thing.

Anybody have a solution?

[Jibidiah]

I would really like some help with this because it’s happening on all the macs in my teacher’s class and we really don’t want to use Unitron

Same here.

It happens whether I start it from within Unity or click on the monodevelop icon in the Unity applications folder.

I checked to make sure I’m up-to-date with the latest Unity (3.4.2f3).

Anyone have any idea how to fix this?

Thanks.

I am having the same problem. Monodevelop will open from the root account where it was installed but not from any others.

Same issue here, driving me nuts!

It looks like it’s a permissions thing…

Right click on MonoDevelop in the Finder and select 'Show Package Contents", right click on the ‘Contents’ folder and select “Get Info” down at the bottom of the info window, for ‘Everyone’ change the ‘Sharing and Permissions’ from ‘read only’ to ‘read and write’. Finally click the wheel icon at the very bottom and choose ‘Apply to enclosed Items’.

Hth,

Just had a similar problem on a first time install on a mac.

Can vouch for the permissions theory, i found setting the account I was attempting to open MonoDevelop in to admin status worked fully. Sammer’s solution allowed me to open the program, however it only displayed the graphics correctly, all the text displayed as gibberish.

Hey Sammer your solution worked like a charm…thank you!

[Martin_SHP]

We just had the same issue in our Mac lab. Managed accounts fail to run Monodevelop, while Standard accounts on all machines (OS X 10.6) launch the app, but with all font display missing (screens show squares in place of each character)

Setting the Contents folder to Read/Write for everyone as described above fixed it, though I’ve had to change the account management on all of my machines to bypass Parental Controls.

OMG IT WORKS!!!

BTW: Don’t forget to click on the weel thingy!

[markfrancombe]

One more thing… if none of the above work.
Same fix really but if you only have “everyone” in the sharing and permissions box, then click plus + sign, and add your name, change to read and write and then cog “Apply to all enclosed”.
do this for both the app itself and the contents folder.

Wow, thank you so much. It really helped. This is so much better.

Unfortunately, the permissions fix did not work for me.

here’s my situation: On OSX 10.9 This issue started after I stupidly changed the name of the MonoDevelop.app. I changed it back but the damage is done. I’ve corrected the permissions, I’ve uninstalled and reinstalled several different versions of Unity. I’m tried to delete every remained Cache, Preference, and Log that I can find related to Unity or MonoDevelop but nothing has worked.

heres the log from when I launch MonoDevelop:
Starting MonoDevelop-Unity
