garageband won't start

Nope, its the same. I tried the right-click opener through garageband icon, and Ive tried to click directly on older projects. Happens exactly the same thing 😟

Yes I've restarded the computer etc.

I did create now a Guest User account and it does work with that account 🙂 . But still doesn't work on my regular account.

What I can recall it said often when I was playing/recording with garageband "Disk to slow....something something...10005". It just paused and this message came up. I pressed OK and it continued.

I have like 100GB free on the hard drive. Not installed or updated any software as I can recall. No plug-in or soundfonts. No drivers for audio inteference.

It does work with Guest User account. Perfectly normal.

At first I thought there was something wrong with the hard drive because I had the computer on my bike and it was pretty shaky/bumpy ride to the rehearsal space... and after this it stopped working. But everything else and all the other programs work on my computer...

Edit: I do use a Steinberg 44 external soundcard for recording...but I have not installed any new updates etc for it since I got it.

It worked!! I deleted the preferences file. Then I deleted the containers folder. Then I restarted my computer and I could use Garageband normally.

but now something is weird again, let me describe the events that happened....

So I jumped into the project that I was most recently working on. I recorded lots of instruments and vocals and created several new channels. Everything was working perfectly. Then I quit Garageband, and turned of my computer.

Came back after couple of hours, turned on my computer. Everything OK. Then I turn on Garageband and it starts loading the project but does crash halfway through loading. My whole computer does a freeze and I have to restart it manually.

Now after I restart it manually I start to experience severe lag, not only in Garageband but all programs. Sometimes it does manage to load Garageband but when I try to play anything it says "System overload or Disc to slow 100001-". I have to shut down the computer manually several times because the computer does a freeze. The computer makes this "loading noise" all the time even when not running a program. Like an old car trying to start...the loading noise makes several "false starts" before it gets going and then I can use a program. Getting into Safari and writing this has been very difficult.

I tried the Guest Account and it seems to be the same over there aswell. Difficulty running any program.

I have 240GB free disc space, can it still be something with this? Seems maybe my computer or hard drive is done for, maybe I should get a new computer?

Anyways thank you so much for the help. I was so happy when Garageband started working again hehe (for a while till it crashed again 😝).

Even when using Finder I now experience severe lag...

I did the verify disk and repair disk. All is OK now it says...but I still this lag. Its like if the computer works normally for 2 min when I start it up, then I get this heavy lag.

Do you know if the newest macbook air 13 works good with garageband? Since it has flashdrive and usb only I think the harddrive would be more resistant to shakes/bumps. No moveable parts.

I record in my rehearsal room and make demos. Here is example of our production: www.soundcloud.com/sexypenisband

Would a macbookair be enough for this kind of production? Recorded with external soundcard

Ok my computer works now. I have no idea what was wrong but let me tell you what I did.

I restarted my computer then pressed CMD+R and I pressed "Reinstall OS X Yosemite". It reinstalled the system and now its working. We'll see for how long this will work but its working right now, all the programs 🙂

Thank you for the help and your time, I was amazed how quickly I got help in this thread and the friendly atmosphere.

Cheers
