Having sound issues with Mid 2011 iMac 27"

Having sound issues with Mid 2011 iMac 27". It has 10.10.2 OS X. Could this the issue and if so how do I revert to 10.7.3

It is almost impossible to diagnose sounds over the internet, however here is a link to some failing HD sounds. If one of yours be happy, at any rate take it in for service. If you got AppleCare or it's less than a year old it's covered.

I am having sound issues with Pottermore while using Safari 6.1. I once muted the sound and now can't unmute it even though the icon tells me it's unmated. I can hear samples of audio books in the store section. Any ideas?

I am having an issue with Outlook 2011 for Mac.

Emails show up in my Trash folder that are not trash or junk. How do stop the Trash folder from snagging my emails?

I suggest you post your question on Microsoft's forums for their Mac products, as it's their software you're having issues with: http://answers.microsoft.com/en-us/mac

YouTube Fullscreen Choppy Playback with mid 2011 iMac

Hello,
I have a BTO 27" iMac with 3.4 GHz i7 and the 6970M 2GB graphics card. Everything else is stock. The problem I'm having is that with every YouTube video at any quality (240p, 360p, 480p, 720p, 1080p) played in fullscreen, the playback is choppy. It's not my internet connection because I've even let the video load completely. Also when I exit fullscreen, it's perfectly smooth. This is very surprising to me. However, with Vimeo and other flash videos at fullscreen the playback is nice and smooth. Has anyone else experienced this? What do you recommend? In the mean time I've been doing the scroll to zoom to fullscreen videos.

Thanks for your reply. What you restated is correct. With any browser (Safari, Chrome, Firefox), YouTube within the window plays fine until I click fullscreen. When I exit fullscreen it's back to smooth. I checked the Graphics section and everything looks fine. This is what I see:

I just did a complete shutdown and booted it up again. Still choppy. I'm guessing it's an Adobe Flash thing but if no one else with the same setup as my iMac is having the same problem maybe I should bring it up with Apple.

Rattling Sound with Mid 2011 iMac 21.5 inch

Hi There
I basically have this rattling sound coming from my hard drive, and I am not sure what to do, or how to fix it, can someone tell me what to do? I have a 1TB HDD 7200rpm, 16GB RAM, and is insured with AppleCare.
Thanks

1. Backup
2. Click on > Apple - Support - iMac 1TB Seagate Hard Drive Replacement Program and see if your iMac qualifies for this program.

I'm having multiple issues with my 2011 intel based macbook pro

It's the i7 with the gigabyte nvidia card and a terrabyte hard drive and 4 gigs of ram i have no idea why its crapping out on my after only 6 months but when gaming my screen will randomly go to sleep and this is kinda of solved by pressing the esc key or power key but i would prefer it did not do this mid game, my mac book also starts making a loud buzzing/humming noise at random times even sometimes when the system is idle, it comes from near the left speaker (not through it)
i am not covered by warrenty and im really hoping i can fix these problems conviently or cheaply
another important note is that i am dual booting windows and mac os x

Don't install MacKeeper.
It sounds like you're having a lot of different problems. Rather than trying to troubleshoot each one, you should first boot in safe mode by restarting and holding down the shift key until the Apple logo appears. Some things won't work in safe mode, but you should at least be able to tell whether things are better or not.
If things do get better in safe mode, then at least some of your problems are being caused by third-party software you installed. If there's no improvement in safe mode, then you should back up your data and reinstall the OS.
In order to back up, you'll need another Mac in working order with a Firewire port. Start up the MBP in Firewire target mode by holding down command-T when you reboot. You can then connect it to the other Mac using a Firewire cable, and it will function as an external drive

Having sync issues with Outlook 2011 since upgrading to Mavericks

Hi All,
My work Macbook Pro 13" is having issues syncing my inbox and sent mail automatically. It's a hit or miss if I recieve emails in my inbox in a timely mannor with out pressing the Send/Recive button (even when i press it takes minutes to update). My Sent Items can show up an hour later even if I hit the Send/Recieve button.
All my mail is there and shows up/syncs on my iPhone quickly. I upgraded to Mavericks right when it came out and have only been having these sync issues for the last week or so.
I've cleared my mail cache and that didn't work. My calandar reminders and contacts don't seem to have any issues and no other apps have been preforming slow or strangely.... just my VERY important work email. My tech guys are stumped and I wanted to try you guys before they do a major rehaul of my system
Thanks!

A new Outlook Identity will most likely solve your issues. If you have any data under "On My Computer" folders, see this link:
How to move your data to a new Identity
BTW, how much free space on your drive? Use Disk Utility in Applications/Utilities to find this info. You need a minimum of 10% free but 15-20% is recommended.
Outlook gets very sluggish when you are low on disk space. If you have a bunch of older Identities from previous rebuilds you can delete these to help free up space.

I'm having sound issues with my iphone 3gs

Ok, so the speaker sound on my iphone 3gs has stopped working. The only sound I do get is my ringtone and if I play a voicemail. I also do get sound when I plug headphones in. However, whenever I get a text message or an email, my phone vibrates even though my ringer is on. I don't hear the click sound when I unlock my screen or type anything. If I push the volume side buttons, the small, black volume/ringer box does not appear and if I play music the volume adjustment setting is missing. I've reset my phone, I've backed it up, I've messed around with the sound settings, my software is up-to-date, I've tried cleaning my headphone jack with a q-tip and nothing has worked. I have no idea why the sound stopped working since the speaker sound worked earlier today, I haven't dropped it, and I've only had this phone for about a year. Any help and/or advice would be greatly appreciated.

I'm sad to report that I have the same issues between three to four times a day. Before I got my iPhone 4S (first iPhone I've owned, btw) I used to have a Sony Ericsson C902 that I operated along with a bluetooth headset HBH-DS205 that used to work perfectly together. Now, with the headset and the iPhone 4S I keep noticing that the connection breaks and all I can do to restore it is to turn the headset off and on every time. I listen to music all day long on the headset and this issue can get to irritating levels. Also sometimes I feel stupid as at work I'm one of the few 4S owners and, the iPhone being a state of the art device, my coworkers get to see me scrambling to figure out whether I need to bring the phone up to my ear or just one of the earpieces to my ear. The headset also has a answer/hang-up button that as of late, for the same reason, I cannot know for sure will start or end a call. I would hate to be forced to drop the headset as I really love it too.

I have a mid-2011 iMac running Mavericks. When I click restart the computer goes to a white screen with a spinning circle and does not go any further until I hold down the power button to turn it off. What do I do?

Ok, sounds like the safe mode boot worked... You probably don't want to always be in safe mode though (some reduced functionality) so does it do a normal boot now? If not, you should then reboot into safe mode and run Disk Utility. Then select Macintosh HD on the left hand side, and click the Verify Disk button. If needed, it will ask you to Repair Disk. If there are errors found, Repair Disk again until there are none. Then try another normal boot and reply with result, wether good or bad.

My Mid-2011 iMac with pre-installed Lion can't load AHT (Apple Hardware Test) over internet

I have a Mid-2011 iMac (3.4GHz) of which Apple's Support document for the Apple Hardware Test (http://support.apple.com/kb/ht1509) says:
Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.
Well, this doesn't work for me. My Mac is on a DHCP-supporting router which has constant internet connection. Yet, when I turn off the Mac and then on again, holding the D key down even before the screen turns on, the Mac does indeed react to this key as it's then turning the screen on and taking another about half minute before it continues with the boot process along with showing the Mac symbol. Without the D, the Mac symbol comes up quickly.
So, it appears that the iMac is indeed trying to get AHT over the internet. Just that it doesn't succeed in it, and probably timing out after a while.
Any suggestions how to fix this?

Re
extract from kb article
PPPoE (where there is no router handling the PPPoE connection)
No
No
Captive-Networks (where you click an "Agree" button to access the Internet)
Yes
No
Proxies (where specific proxy servers must be configured in network preferences)
No
No
Certificate-based authentication / 802.1x
No
No
try check if you are in that case for your internet acces ?
could be a firewall problem too , if is possible try desable firewall ( or any internet filter )
no you can not see a wifi selection if you are wired ( using cable )
by the way D key for AHT need to be pressed AFTER start up sound , and hold at min one minute

Mid 2011 iMac continuity issues!

I have recently upgraded to OS X Yosemite on my Mid 2011 iMac, but continuity doesn't seem to work on it. Is my iMac to old?

I did install Yosemite in my 27" iMac (Mid 2011) last Friday and after 6 hours of use I got display issues. After the iMac comes back from sleep I get pixelated blocks in random areas that stay on background until open a new app window. Two days ago my computer frozen and got pixelated blocks all over the screen. After restart got the graphics problem box and asked me to report it which I did. I restored Mavericks from my time machine and everything was working fine again. Then yesterday afternoon did a Yosemite clean install in my iMac and this morning got the same display issues and computer completely frozen. I restored Mavericks AGAIN and everything is working fine so far!!! I'm gonna stay with Mavericks until Apple release a fix for my issue.

Is there a way to run a 2005 PreSonus Firebox(with the firewire) to a mid-2011 iMac 0SX 10.7.2? It says its no longer supporting Power PC? Anything I can do without spending more money on new equipment or a new computer? Please help me.

Nevermind, I got it working.
I ended up extracting the new vob within MPEG Streamclip, which gave me an m2v and an aiff audio. I multiplexed those two back together in FFMpegX which gave me a complete VIDEO_TS folder with BUP and IFO files I needed.

Is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

is there a way to run a external ssd with my mid 2011 iMac hdd in a raid configuration and basically have a fusion drive

A Fusion Drive is not a RAID; it's a CoreStorage logical volume group. While it's technically possible to do as you suggest, there would be little or no benefit from it.

What system did my 'Mid 2011' iMac come with?

I have upgraded to Mountain Lion but I'm wondering if the system actually came with Lion or Snow Leopard?

mulgravebrad wrote:
A friend has asked if he buys the machine can he reinstall Snow Leopard on it?
Good question. The Mid 2011 iMac can run Mac OS X Snow Leopard without any problem, but there's a problem: you need a special Snow Leopard version that it's only available on the Mac OS X DVD that Mid 2011 iMacs have got.
If your friend tries to call Apple to try to get DVDs for a Mid 2011 iMac, Apple will ask him/her for the serial number of the iMac. As your iMac came with Lion, Apple won't send him/her the DVDs he/she needs to install Mac OS X.
In conclusion, it's possible to install Snow Leopard, but things like a possible firmware restriction and the lack of the Snow Leopard version that your iMac needs may trun this into a very difficult task
