No, your Mac is not possessed. And Yes, it’s trying to tell you something!
A looping three beeps in between three seconds during startup is your iMac’s way of telling you that the operating system you’re trying to boot into is incompatible with your Mac hardware.
In other words, the Snow Leopard disc you’re trying to boot from contains a version of Snow ...
You can turn off your iMac (and your macbook) screen without sleeping via the following keyboard shortcut:
⌃ + ⇧ + ⏏
(Control +SHIFT + EJECT)
Machines like the Air and newer MacBook Pro with no optical drives have the power button in the same place as the eject key and it works similarly for display sleeping shortcuts.
Is it possible? Yes.
Will the benefit outweigh the costs? No.
Without going into a lot of detail, and at the risk of oversimplifying things, in the early days mining bitcoins was easier than it is now. And, as time goes by, it will continue to get harder.
Another contributing factor is that the kinds of calculations needed to ...
I have had this problem in the past. I found my answer here. http://osxdaily.com/2013/12/27/fix-there-is-no-connected-camera-error-mac/
Open terminal from the utilities folder in the applications folder. Type sudo killall VDCAssistant into terminal and click enter.
Then, enter sudo killall AppleCameraAssistant. That should do the trick.
This cable costs $39 retail. At this price I am expecting better
performance for charging than what I'm getting here. How could I
diagnose this issue?
There's nothing to diagnose because everything is operating as it should.
The problem is not the cable (it's irrelevant, actually) nor the iMac as it's only capable of delivering up to 15W of power via ...
Because OSX manages memory (as does Windows) it is often difficult to tell if performance issues are caused by memory limits. Technically, you really want the OS to capture all the available memory and allocate as needed, in which case, you would see all of the memory being 'used', even though there may be memory available but not allocated by the OS.
Check out the Mono Project. It may be what you are looking for.
MonoDevelop is a cross-platform IDE primarily designed for C# and other .NET languages. MonoDevelop enables developers to quickly write desktop and ASP.NET Web applications on Linux, Windows and Mac OSX. MonoDevelop makes it easy for developers to port .NET ...
Thunderbolt-equipped iMacs prior to iMac (Retina 5K, 27-inch, Late 2014) (see this document), like your iMac (Mid 2011), support Target Display mode:
Target Display Mode lets you use your iMac as the external display for
another, “primary” computer.
NOTE: This won't work for iMac (Retina 5K, 27-inch, Late 2014) and later iMac ...
Do LAN transfers use both Ethernet and WiFi by default?
No. The default action is to use the one with the highest priority. This is usually done by the order of the interfaces that you specify in Network Preferences. Following that, the next order of priority is network latency.
If not, is there a way to enable transfers to use both?
What you are ...

Shutdown vs. Sleep is a constant question.
It used to be that shutting down the early OS X machines caused issues with timed log cleanup routines. That's pretty much a non-issue these days as the OS recognizes when the routines haven't run and will reschedule them.
Another concern has been restarting to free up memory or just make the machine more stable. ...
Here is a easy way to change the icon.
Remove Sublime Text from your dock.
Open two finder windows. One with Applications and one in the folder with the new icon. Like so:
Then click on Sublime Text and press CMD + i, this will bring up the Info Window for the App (Sublime Text). Like so:
Now, it's as easy as this: Drag and drop the new icon onto the ...
I found this to solve the problem for me, thanks to Major Hayden!

Occasionally the progress bar that appears under the downloads folder does not go away as it should when the download completes. You should be able to remove it by simply restarting the computer or running
at the command line (Terminal). This should reset just the dock process without having to restart the whole machine.
There are a number of possible reasons, and the system actually logs the cause of each 'wake from sleep'.
Open a terminal and enter:
syslog | grep -i "wake reason"
(or, on Sierra or newer log show | grep -i "wake reason")
This may take some time to return a result, but when it does, you should get a series of lines that look something like the following:...
For me, this partially fixed things:
Close all open apps.
Move ~/Library/Preferences/com.apple.recentitems.plist (and ~/Library/Preferences/com.apple.recentitems.plist.lockfile if it exists) to a backup directory.
In my case this fixed the recent items lists under the File menu in each app and the Apple menu. But the context menus on Dock icons ...
It's way simpler than that guys. The brightness on the display is controlled by simply pressing:
Control+F1 OR Control+F2 to adjust brightness on your secondary screen (the one without the menubar).
F1 and F2 to adjust brighness on your main screen (the one on which the menubar is located).
If you have adjusted settings in System Preferences for the ...
If you have the 27" iMac MacTracker says it supports up to 32GB, even though Apple only says it supports 16GB. The 21.5" iMac can only support 8GB either way. OWC, a reputable memory retailer, started selling 32GB upgrade kits for the 2011 iMac last year.
Your first stop should be the energy saver preference pane. Dial down the Display sleep slider as short as you can stand it.
If you don't want to wait for this time out, you could also set a hot corner and black screensaver so you could use VNC to set the mouse pointer to the corner to engage a black screensaver so the screen is as dim as possible until the ...
Sorry to hear you’re having problems. I hope the following clarifies things for you, but if these instructions do not help, you can always post specific questions about any problems you’re having.
The reason for your confusion is that the instructions for resetting the System Management Controller (SMC) will differ depending on whether your device:
This thread is a bit old, but in case someone else finds themselves looking for the answer, this just worked for me:
To move / re-install your licensed copy of Microsoft Office 2011 for Mac on a different computer / OSX installation, and re-authorize it without the license / serial / key available, copy the following from the old machine to the ...
If you want something more elegant than a book under the iMac, you can can add vesa mounts to your iMac and Thunderbolt display and then attach it to a desk or wall mounted adjustable monitor arm. There are many to choose from but here is one pictured below to give you an example. So you could technically mount both or just one to a VESA stand. Note that ...
No you don't need PC hardware since Yes you can delete OS X entirely after getting the drivers installed from Boot Camp on OS X.
Follow the directions for creating the bootcamp USB key that comes with bootcamp (you'll need an 8GB key). When you boot from the bootcamp key and it gives you disk utility just delete the OSX partition (I believe this is an ...
On your iPhone, go to Settings > Phone > Calls on Other Devices > un-check the Mac. Then switch off the "Allow Calls on Other Devices" toggle switch and restart the phone.
Also worth mentioning: simply switching off the "Allow Calls on Other Devices" toggle switch does NOT solve the problem - the Macs remain in the audio options list even if that option is ...
I am a firm believer in avoiding software "hacks" to fix hardware issues. To fix this problem, you need the sensor. Unfortunately, as you have found out, your SSD doesn't support this connection.
However, OWC makes an digital inline temperature sensor. Basically, it goes between the SATA power cable and the SATA power connector of your HDD/SSD. The temp ...
Why does it feel so slow?
Your iMac has a 1TB 5400rpm SATA Hard Drive and this is what’s causing the bottleneck. Your mid-2010 iMac would have had a 7200rpm Hard Drive. To fix this you really need to address this bottleneck.
The 'easiest' solution
Since your iMac has two Thunderbolt 3 (USB-C) ports that support speeds up to 40 Gbps (via Thunderbolt) and ...
