Brand new imac 27" keeps crashing randomly in mavericks while idling, using firefox, transferring files, etc. Reformatted and reinstalled everything from scratch after 15 plus crashes a day. Crashes now only 4 times a day. Help!

Brand new imac 27" keeps crashing. I'm running 10.9.2 with all software up to date. It will crash on file tranfers to/from/between external drives, web browsing, word processing, video editing, and even while idling. It used to crash every 15 minutes when I first got it but I reformatted and reinstalled all software. Now it it still crashing albeit less often. This is extremely frustrating because I have no idea what I can do to prevent it from happening!
Any ideas/help would be greatly appreciated.

Hmm thanks for the input. Alright. I uninstalled Avast. Was good for an hour or so. I was doing some file browsing and crashed again. Got this message.

I can print on y HP Deskjet f4580 from my IMAC with Lion 10.7.5. I've updated the print drivers and my OSX and reinstalled everything from scratch too. No joy. Help?

My HP Deskjet f4580 won't print from my IMAC despite updating the print driver and OSX 10.7.5 Lion software. Printing is fine from a different computer. What else should I try?

My new MacBook Air keeps shutting down the screen while I use it

My new MacBook Air keeps shutting down the screen while I use it and has to be rebooted. I took it in to the Genius desk at my local store, but they couldn't find anything wrong and said that they have never seen this problem before.
I Spoke to the IT support guy at work. He has the same problem with his new MacBook, but not with his older one. He suggested that it is a software issue with all new MacBooks and is connected to the timing of it going into sleep mode. Does anybody have a solution? Apple doesn't seem to have one.

Try a SMC reset.

Can I use Adobe Photoshop CS4 Extended on my brand new iMac? I had PS on my old Mac using the student licensing.

About four years ago, I purchased Adobe Photoshop CS4 Extended while I was in undergrad. I downloaded it to my Mac. Since then, I've purchased a brand new iMac. Can I use this same software? I know it's been four years so the software is very updated, AND my new iMac does NOT have a cd drive. This may all be in vain. I'm just clueless! Thanks!

Emalexander89 you are welcome to install Photoshop CS4 on your new Mac. You can download a fresh copy of the installation files at Download CS6 products.

I recently transfered my Thunderbird Profile and messages folder from XP comp to a Win 7. Now I can't open my inbox messages. Help

I had Thunderbird installed and operating fine on my XP computer with my messages kept in a truecrypt folder. (Not default location) I have a new computer with Win 7. I read support files that directed me to move my profiles folder from my XP computer into the newly created profiles folder for the Win 7 computer. Then I copied my truecrypt folder to my new computer. Then I went in to the account settings for all 4 email accounts I keep track of and fixed the Local Directory for message storage under server settings to point correctly to my messages folders in truecrypt folder.
Now when I try to access my inbox for any of the email accounts I get the working circle (old XP hourglass) infinitly. Ultimately I never get to see any old or new messages.
I did notice that if I select the inbox of any email account and then select edit folder properties, the location is blank but it will not allow me to change it or correct it.
Any ideas?

This was the only answer that came up on my search, so please don't get so testy. I don't have my iphone with me, since I switched phones. Apple support will not let you call them, get a call from them, chat with them, etc without first putting in your serial number. What next- anyone else have an idea?

Black screen on brand new iMac 27? I hit power, hear tone, a voice to assist with set up and no video...not even a flicker.

Why is my brand new iMac locking up?

My i7 2.93 iMac with 16gb RAM keeps freezing while I'm using ableton. I've uninstalled and reinstalled everything from software to drivers to the OS and NOTHING seems to work. I'm thinking it might be overheating?
i submitted crash logs to ableton tech support and they say that ableton is not crashing and that it looks like nothing is wrong with my software. i even tried using the beta version and old versions to try and isolate the problem. no luck.
any advice?

There are several threads on here where people have experienced problems when running with 16gb RAM (here's one: https://discussions.apple.com/thread/2473276?start=0&tstart=0 )
Although it mostly concerns random shutdowns I have also seen seen others reporting lockups. It seems a quick solution - just to see if it is a RAM problem - is to drop down to 12gb RAM. If it then runs OK I'd see if you can replace all the RAM to one of the few that are recommended - Samsung RAM, from memory (no pun intended ), seems to be problem free, and I believe there are others.
iMacs seem to be very particular about what make of RAM is installed.

What's with the brand new imac's not being able to handle 3 tracks in garage band? This is crap!

I have been so dissapointed by Lion i'm thinking about selling the brand new Imac. No Rosettta?! So i cant use Final Cut express anymore or CS3, and I don't WANT TO UPGRADE> And Even Garage band cannot play more than 3 tracks without saying there are too many? I can work better on my 2008 macbook!!!!

And Even Garage band cannot play more than 3 tracks without saying there are too many?
There must be something wrong. A brand-new iMac should really perform better.
What model did you buy (Processor, how much disk space, how much RAM)? Can it be, that your harddrive is too full with less than 15 GB of free space, or the iMac has not enough RAM? Lion needs a bit more memory than Snow did.

I can't get my iChat to work on my brand new iMac.

I am trying to use my iChat on my brand new iMac intel. It looks like I have an account, but it is disconnected. And I can't seem to connect it...or find any resources online to explain why. Any ideas? Cheers, Erik

Hi,
So in iChat > Preferences > Accounts you list something in addition to the Bonjour Account ?
If you click this account to Highlight and then make sure the account Info tab is the active one - is the "Use this Account" check box ticked ?
What message to you get if it isn't and you tick the box ?
What sort of an account is it ?
It will list AIM whether it is AIM, @mac.com or one from MobileMe.
Pic of Check box
Notes:
Apple allow passwords over 16 characters in registering for a MobileMe account and @mac.com names.
However the AIM servers can only make use of passwords up to 16 characters in length so you may have to shorten it.
In the pic you can see my Screen Name does not have a @something.com (it is a plain AIM name)
However at AIM you can also register Email address as Screen Names
GoogleTalk
If you have a email account with Google you can Enable Talk as an Option of your Google Account page.
This will let you chat in the Google Mail Web page.
You can also use this name in iChat.
However you must enter the name as it appears on any Google page when you are logged in.
So if you are [email protected] it should be entered that way. Same for an @gmail.com ending. (The Mail app does not seem to mind but iChat does - well the Talk server does)
Other Jabber accounts/IDs
Like AIM valid Names you have to have registered from a Jabber ID with a server before you get to enter it in iChat.
With these Jabber accounts the iChat app will presume the server name is the last part after the @ (they look like email addresses)
So in this case if you are [email protected] iChat will extract the aJabberServer.Com to Move to the Servers settings tab info.
(The exception is Google which is also a Jabber server).
Presumably you did this through the Start Up Screens as in these pics
http://www.ralphjohns.co.uk/versions/ichatvers4/howtoStartiChat.html (iChat 5 is exactly the same at this point)
If none of this makes any sense or does not match what you remember doing could you detail that as much as possible.
I may receive some form of compensation, financial or otherwise, from my recommendation or link
There are in fact over 360 pages here on iChat.

Firefox crashes or freezes unexpected while watching/using flash contents

Firefox crashes or freezes unexpected while watching/using flash contents. Particularly, when I need any flash content. It freezes up so that the only option will be to force quit the firefox.

I've noticed the crashing increasing with the newer versions. The worst thing is when I'm writing a long email and then go to a page with flash and ff locks up and then crashes. I use IE now for most flash content or mission critical emailing but IE's interface is poorly laid out so I don't like it. I've tried FF with the plugin container and without it and it crashes either way (more often without the container). I use adblock and firebug. I wonder if ppl experiencing this prob are using those plugins too.

Photoshop CS6 keeps crashing. I am using a brand new IMAC, I have 16GB RAM recently updated as it was running slow with 8GB and lots of hardrive space. When it crashes, i lose all my presents and it changes my preferences, it also fails to save or produce

Photoshop CS6 keeps crashing. I am using a brand new IMAC, I have 16GB RAM recently updated as it was running slow with 8GB and lots of hardrive space. When it crashes, i lose all my presents and it changes my preferences, it also fails to save or produce a recovered file despite settings asking it to do so every 5 mins now. When i try to report the problem, it says it has found an issue and gives me a link to a solution....but wont let me click on the link.... PLEASE HELP! It's killing my productivity.

If the crash started right after you added RAM, it could be a bad Ram dimm. You can try this - change the amount of RAM in Photoshop to 4G, this should stop Photoshop from using the higher ram. If it doesn't crash, it's probably the ram. Or run a diagnostic app. You don't say when it crashes, what you're doing when it crashes - it there a pattern? Did it ever work on this computer? Did it work on your previous computer? Without a lot of data, it could be related to the new computer... What OS version? Did you recently update it? Have you updated Photoshop to the most recent update?
Do you have any plug-ins loaded? Try restarting Photoshop, and immediately press & hold the shfit key to turn off plug-ins.

Final Cut X Keeps Crashing with Brand New iMac

I have a brand new iMac (3.2GHz Quad-core Intel i5, 8GB SDRAM, 1TB ATA, 1GB GGDR5) and have done almost nothing on it before downloading the trial version of Final Cut Pro X. I was used to Final Cut 7 and wanted to try out X before purchasing.
I have one project and one event in Final Cut X, it's only a 4 minute video of mostly images, some video and two audio tracks. Every time I try and add any effect like a simple crop/Ken Burns or cross disolve to one of the pictures, Final Cut crashes.
Most of the stuff on here says to delete your preferences or repair disk permissions. I have repaired disk permissions and it still crashes. And as far as preferences, it says to use an app from Digital Rebellion to delete any preferences but I don't think I even have any to delete. I went to system folder -> Library -> Preferences and looked for any FinalCut.plist files to delete and there are none.
I'm wondering if certain photos I'm using are corrupted, but it would appear they all are then. I imported them from a file, would it help to import them from iPhoto? Is there something else I could do to fix those photo files? Or anything else I could try to get Final Cut from crashing?

Thanks for your reply Russ. I'm not sure what you mean by Preference Manager. Am I looking in the correct place for preference files? (Users > Library > Preferences)
Are you saying that even though I may not find them in the Prefereces Folder, an app like Digital Rebellion would help me find them?
I'll try testing a new project but the problem is I can't isolate the problem clip because it seems to be crashing anytime I try and add effects to any photo. Do you know of an app that I could run photos through to "uncorrupt" them?
And when you say create a new user account, you mean at the system level of the computer?

Brand new iMAC keeps hanging

Hi All
I received my brand new iMAC today - having never had a MAC anything before - decided to switch as fed up of hanging, viruses etc on PCs and also need more multimedia options.
Have set it all up it keeps hanging - for no reason i click on force quit and sometimes it will and sometimes it won't even do that - I am totally confused it has done it to me on MAC Office, iCalc, i photos, i tunes etc etc
Do i have a dud machine am i doing something wrong???? Please help.
Cheers

Kazzaboobers,
Welcome to the forum. Chances are you don't have a dud. In case you haven't read the manual I would recommend doing so before playing with your machine, you will be surprised what you learn.
Also when you mention the machine is hanging please describe with a little more detail so we can understand exactly what you mean.
You are covered by 90 days for free telephone support, if the problem persists take advantage of the support and give Apple a call. In the rare event you did get a dud they will replace the machine within 14 days of purchase.
Last IMHO it is a good idea to get AppleCare, this gives you 3 years of phone support and an additional 2 years of warranty. You can find it online (Amazon for example) for less than Apple charges.

Brand new imac 27" keeps crashing randomly in mavericks while idling, using firefox, transferring files, etc. Reformatted and reinstalled everything from scratch after 15 plus crashes a day. Crashes now only 4 times a day. Help!
