This is a workaround. I have a similar problem to the OP. I found that I can make the display sleep and stay asleep via the command line: pmset displaysleepnow In contrast, the external display wakes immediately after sleeping when I use the hot-corner method. Since display sleep problems can have many causes, my general advice is to try different ...

What worked for me was to go to Store>Sign Out Once I was signed out, I was able to sign back in and purchase/install apps correctly. Not sure why this happened, but it fixed it for me.

I installed 2x 2GB DDR3 1333 PC3-10600 into a late 2009 mac mini. Running 10.10.2, which struggles on the default 2GB. It started up fine, and apps were so snappy, but then the crashes started. The machine is completely unstable, with kernel panic errors every 30 odd seconds forcing a restart. Sadly the original 2GB RAM has gone back in. I'd recommend ...

Just for grins and giggles... Did you verify that your cable and network port are good? First thing to try is moving your connection from whatever port on the switch it is on to another. Sometimes a port on the switch just may be bad. You will also want to verify the cable. If you have access to another computer or a laptop, remove the patch cable ...

I agree with bmike that since we don't know what the nefarious people have you do, it's next to impossible to diagnose the problem here. However, I am going on the premise that you can turn on your computer but you just cannot log in - meaning enter your username/password - as you described. To reset your OS X password without an CD you need to start up in ...

At first glance, I am wondering why you are using an HD 4000 driver for an AMD Radeon HD 6970M chip. Have you tried downloading and installing the AMD Drivers? http://www.amd.com/en-us/products/graphics/desktop/6000/6970

In addition to the above, other software solutions are Jinx, who offers a product called ScreenRecycler. Couple this with a VNC client like TightVNC or JollysFastVNC (from Jinx), you pay once for the main computer, and can use any number (one at a time) of other computers as a remote display. This software is currently in Beta, and I found that after 5-10 ...

Without knowing the steps you did, it's hard to guess what the villains had you do to your computer. Why not power it off and then get some help. You'll need to know the following things to make a good decision on what's next: When is the last time you backed up your Mac and is that backup still viable? How much time/budget do you have to learn how to ...

Load average is CPU based, not GPU based. The numbers represent one, five, and fifteen minute averages of the load on the CPU. A single-core CPU is like a single lane of traffic. Imagine you are a bridge operator ... sometimes your bridge is so busy there are cars lined up to cross. You want to let folks know how traffic is moving on your bridge. A ...

according to Mactracker the mid 2007 imac 20inch has: Maximum Memory 6.0 GB (Actual) 4.0 GB (Apple) Memory Slots 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM you should also make sure that you always have the same amount on both slots in your case two 3gb however 3gb rams are rare therefore more expensive


1

Crucial, UK state that 4GB is the maximum amount of RAM that your iMac officially supports. If you put more in and it worked then this could be seen as a 'bug', and wouldn't be supported by Apple. Such abilities could also be revoked through software/firm was updates.

thanks for the suggestion. I have now tried the hardware diagnostics test, however the short and full tests both cam back clear so no issue with the hardware. I bought it from an auction site that specialise in liquidation stock and repossessions e.t.c so have no idea who previously owned it. I would assume it would be illegal to sell somebody's computer ...

In order to try to localise the problem, try adding an additional user to your iMac, and see if this new user also has no sound. If the new user has sound, then you can be sure it's not a hardware problem. If the new user has no sound, then it looks like it's a hardware problem.

This happens to me once. Have you used 'Text' tool from the markup toolbar? If so, the font you used before might not be available with your current setup. If you remember which font it was, install it. Preview.app should open fine after.

Screensavers were developed do deal with issues that affected CRT displays. As nobody makes them anymore, and LCD displays don't have the same issues, we no longer need screensavers. A screensaver running on a flat screen monitor just looks pretty - there is no difference to the operation. Open System Preferences. Go to Desktop -> Screen Saver and set the ...

To change your Screen Saver go to  > System Preferences... > Desktop & Screen Saver... From there you can set the screen saver settings. I suspect from your question (although it is not clear) that you have the Word of the Day screen saver selected. You can check it's settings or change the screen saver all together.

in Yosemite you can choose Network Diagnostics by clicking the WiFi icon in the menubar while holding the Alt(option) key. It is the third entry. In Snow Leopard the Network Diagnostics is in the Utilities folder as far as I remember. Lex

Open the Network Diagnostics app located in the /System/Library/CoreServices. Then Run it to check your Ethernet settings, and/or recommend solutions. To be able to run the test, you need to have the Ethernet connection set up in your Network-Location screen. If it is not there set it up using the (+). Newer mind me calling it Comcast, you can choose the ...

Try updating the OS and Silverlight and Flash, and restart your iMac. After the restart you can reset the PRAM.

Another possibility is your backlight may have gone bad. You can check by holding a flashlight up to the display and looking closely. If you can see the icons on your desktop once illuminated with the flashlight then your backlight is out. This is a relatively simple repair you can have done at the Apple Store.

OP here. (made an account). I already found a solution to my question thanks to the editor who used the title "Hover doesn't follow mouse until click" It turned out to be an issue with my RAT 7 drivers. Apparently, Yosemite messed up a few things. An update fixed it, thankfully! http://madcatz.com/downloads/

This is most easily done through iCloud, which should be the same account you sign in to the App Store with. Go to System Preferences > iCloud. If you haven't already set up your iCloud account on your Mac, simply click on iCloud, and enter the username and password. In the right side field, scroll down to "Notes" and tick the checkbox next to it. You may ...

Every iMac from the mid-2007 release onwards can run Yosemite, and the last model that couldn't could also only address 3GB of RAM. So it's almost certain that your iMac will be able to run Yosemite.

I had the same problem, suddenly. Solution? I opened the list of saved networks and removed it, it appeared in the list of networks in range immediately.

Failed hard drive? Select your Apple Menu, hold down the alt/option key, and choose "System Information". Navigate to "Storage". Check the field reading "S.M.A.R.T. Status". It should read "Verified" if OS X thinks everything is OK.

Usually it's no problem to use the ethernet interface instead of the Wi-Fi interface, if the router/access point contains one or several ethernet connectors: Install an ethernet cable between your iMac and the router. Depending on your router you might have to enable/configure its ethernet interfaces. Open System Preferences -> Network. Configure IPv4 of ...

I had and now again the same problem but on a SAMSUNG Series 7 Gamer Notebook (AMD Radeon HD 6970M). It's because of the overheating: it's hardware. Go to an electronics shop and ask there, as it is because of your graphics card.

CNet has an article on the codes returned by the diagnostic test. http://www.cnet.com/news/how-to-invoke-and-interpret-the-apple-hardware-tests/ According to that VH... means voltage on the hard disk.

Skype is one of the most mature VOIP systems, and very much OS X version independent. The Telephone service it offers is superb at very reasonable pricing. You do not need extra hardware, as it can be installed on your existing laptop and smart phones. If you prefer old fashion phones you can heave that. No special setups, or dealing with OS X. Just ...

Yes you can do just that. You could use an SIP line. There are hundreds of phone companies which offer SIP phone services (also called VoIP). Some internet provider also give you the access to the SIP configuration so you can handle your calls the way you like. Check with your provider if they use SIP for your phone line and if so they could actually let ...

OSX 10.7 Lion was not sold on DVD, the first retail OSX version to do so. You can obtain it through three methods: Update your system to 10.6.8 (combo update is best via Apple, or Software Update if you like) and then, using the Mac App Store, purchase a copy of Lion Purchase Lion via the Apple Store website which will email you a download redemption code ...

Probably the virtual network interface of your Windows 7 VM uses "Shared Network". Reconfigure the NIC to bridged network and choose Ethernet or Wi-Fi (like indicated in the screenshot below) depending on your network configuration: if your iMac is connected to the Linksys XAC 1900 via Ethernet choose "Ethernet" if your iMac is connected to the Linksys ...
