I am on OSX 10.10.1. As of very recently (can't be more than a couple of days, else I would've noticed it sooner I think), I am able to quit the Finder by hitting ⌘-Q, which will quit the Finder app, not only close the window. There is also a Quit Finder menu entry, I don't know if that was there before. I asked someone who also uses Yosemite and as expected, they can't do it.
The question is: Why is this suddenly possible, has anyone else experienced it and how can I revert this change?
I've MacBook Air 11" Mid 2013 and I recently clean installed OS X Yosemite on it. The startup was real slow. It took more than 30 seconds to display the apple logo after pressing the power key so I decided to run Apple Hardware Test. BUT THE PROBLEM IS THAT IT WON'T PROGRESS. THE SCREEN DISPLAYS "INTERNET RECOVERY. THIS MAY TAKE A WHILE" AND IT ASKS TO CONNECT TO A WIFI CONNECTION. THEN I SELECTED MY WIFI CONNECTION BUT IT WON'T PROGRESS FROM THERE. P.S. I've never performed Apple Hardware Test before but I've done a lot of research on the internet about it. After selecting WiFi connection, it should prompt me for the password but it won't. 
I want to multiboot my MacBook Pro, I'm trying to make partitions but in Disk Utility I can't make my partitions, only can divide by 2? Why? It's a normal SSD not a fusion drive (SSD+HD)
Now I'm fresh installing my Mac with Internet recovery... (Second time) but this time in disk utility by internet recovery instead click on erase I clicked in partitions and make a partition named Macintosh HD
what I'm doing wrong?
Thanks in advance and sorry for my bad English because I'm Portuguese...
I have an iMac whose wifi connection has always worked very well. Now that I moved in a shared house with a shared wifi internet, the iMac is not able to see our own wifi network, but it is able to see other wifi networks in the vicinity.
I have another laptop with ubuntu installed, and that is able to see the network and to connect, from the same room where the iMac is.
I have tried to make a new connection with the name and password of the network (which I know for sure because they are the same used on the ubuntu connection) but it does not appear in the network list.
I have tried to read more on the internet, but all the thread are related to connections which can not be accessed, while in my case the iMac can not even see the network.
Any advice? I do not knwo what kind of details are needed to define this case, but I will be happy to furnish any necessary data.
Is there anyway to prevent that whatever app change the default app for some kind of files?
As an example, my default app for movies (mp4, mkv, avi, ...) is VLC, and I don't want this to be changed for whatever reasons.
I'm not sure if this qualifies as a legit question here, but I don't know where else to ask.
I have installed the Call of Duty 2 MAC version on my iMac. My system capabilities (RAM, processor, video) are way above the recommended requirements, so I would have expected the game to run smooth.
However, in-game, doesn't matter if I am in the main menu or playing, it keeps freezing for about 2 seconds, every 10 seconds or so. I have set the quality settings to maximum and minimum, and it's the same.
Clearly it has nothing to do with in-game quality settings, as it does this even while in the main menu.
Any idea what the problem might be? I suspect my computer (1.5 years old iMac, 2.7GHz i5, 8GB@1600MHz DDR3, GeForce GT 640M 512MB) has a problem... it does boot slower than when I bought it... and overall it's not as fast.
My MacBook got a small water damage some time ago. Luckily everything still works without any problems except the iSight camera, which is no longer detected. I reinstalled Mac OS X a couple of times since, so I'm sure it's not a software issue. Since a replacement looks pretty cheap and I have all the tools to open up my MacBook, I was wondering, if there are any guides on how to replace the camera. I googled a lot and also checked on Youtube, but could not find anything suitable. How hard would such a replacement be? Can I make sure it's the camera and not some other hardware issue before I try to replace it? On the other hand how much would it cost to have the camera replaced by Apple?
