Thanks to some helpful answers I managed to find the answers to this question. The main cause of this CPU usage is Norton AntiVirus. A Setting in the AntiVirus called 'Norton Deepsight Community Submission' makes it constantly use around 50% CPU, just to collect data and send this to Norton I guess. The other 50% is also caused by Norton AntiVirus, yet I ...

Thunderbolt is a serial bus and can be chained, so only having one port does not mean you can only have additional monitor. Assuming the Thunderbolt monitor has two Thunderbolt ports you can use the second one to chain the two monitors in series Thus having 3 monitors (2 external and one from your iMac). How many monitors (and which resolution)can be driven ...

It is possible to create a Logical Volume Group spanning over more than two disks. I doubt that it will differentiate between fast and slow HDD. The SSD part should work though. To accomplish this put all drives in your iMac and boot to a Mavericks or Yosemite bootable installer thumb drive. Partition all drives as simple volumes with Disk Utility. Then ...

I have been having the same problem. Changing the name of the SSID fixes it immediately. But if I ever happen to switch off the router and switch it back on, the problem recurs and I have to think of yet another name.

Apple recommends using an USB optical SuperDrive to install Windows when the internal optical drive in unavailable. Even though Apple documentation states a late 2009 iMac does not support Windows 10, this may not be true. I installed Windows 10 on my mid 2007 iMac. In fact, this post was entered using Windows 10 on this Mac. Generally, you should install ...

It's an LG LM270WQ1 (SD)(F1). One thread is here: https://discussions.apple.com/thread/5591164?tstart=0 And you can find replacement here: http://www.amazon.com/Apple-A1419-Screen-LM270WQ1-661-7169/dp/B00LEXN39W

That box is clearly trying to install some funny trojan on your computer. (side advice: never download Flash from anywhere that's not Adobe's website, but I'm sure you already know that if you're 'sailing the high seas'.) Unfortunately, there's no way to avoid closing everything. The only way out of this is to force-quit Safari through Force Quit - the ...

I'd like to post an update: I have purchased two Corsair 4GB ram sticks. They work perfectly and passed the memory test. It is indeed a memory compatibility issue - My 27" Imac doesn't take 8GB ram sticks! Thank you all for your help!

After reading some Apple support threads on this topic, I found a hopeful tip that (for some reason) connecting the TM drive before launching Time Machine System Restore limits you to USB 1 speeds (and thence multi-day time estimates), but attaching it after gives you full USB 2 speed. After suffering through about 1% of a backup estimated at 60+ hours to ...

Boot Camp Assistant partitions the HDD so that Windows can be installed. Windows does not support Core Storage, hence the partition is solely on the HDD. Do Macs that have a Fusion Drive support Boot Camp? Yes. Boot Camp Assistant creates the Windows partition on the disk drive instead of the flash drive (SSD). Source: ...

As a work-around use TinkerTool to set your "Recent Items" to which-ever value you like. So far it seems to behave as expected…

I have specifically added myself as a user with read/write access. I had assumed that the 'everybody' group with read/write access would react in the same way as being named separately.

No, the Fusion Drive will not work away from a Mac. The separate components can be formatted to work as stand alone drives but the core storage volume that we call a Fusion Drive will not function without OS X. The data is gone once the Fusion Drive is busted. You cannot recover data once the drive components cease to be associated as a Fusion Drive.

Sounds like your installation is messed up. Are you able to boot in Recovery Mode? Hold both the Command and R keys on the keyboard until you hear the chime noise.

What happens if you save your Photoshop file to a different directory or hard disk? What are the file Permissions? Select your file in the Finder and go to File > Show Info > Permissions It sounds like your file or folder permission are messed up. Also, Repair Disk Permissions (Applications → Utilities → Disk Utility):

Thank you for providing the updated information - however, as I suspected, that is one of the few iMacs from that period that cannot take more than 16GB RAM. I'm struggling to find data on whether it can specifically use 2x 8GB RAM sticks, though your own experiments would seem to say it cannot & that its maximum configuration would be 4x 4GB sticks. ...

I also use netatalk/afpd, backing to a USB-mounted drive. If I partition the drive on OSX first (hfsplus, no journaling), then mount it under Linux, chmod & chgrp it to the TimeMachine userID, and share with netatalk, then I get the same error you report (after "preparing backup", error is "Setting security information: Operation not permitted"), and ...

While this is theoretically possible, if you care about frame rates at all you would not do Remote Desktop for gaming. You would have a hard time getting frame rates above 15fps. Remote Desktop is meant for logging into work computers from home, or controlling headless servers, not gaming.

Pratika Rana is correct: your icon for Safari in the dock is no longer working. Remove it from the dock by dragging it out or by control-clocking and selecting 'remove from dock' find Safari by opening finder and choosing Go -> Applications f of the menu. Double-click to open. Safari, once it starts, will now have a new icon in your dock. Control-click its ...
