I just upgraded to Lion on my wife's MB 13" 2008 unibody and it runs slow and the system restarts can anyone help?
Everytime the mac is left for a period of time it will restart. It also will shut down apps like safari, mackeeper, etc
Hello,
So, it won't boot from the ASD Disc?
Did you put the CPUs back in the same position they were in before?
What kind of Thermal paste did you use?
The Macintosh startup chime is the single note or chord (depending on model type) played when an Apple Macintosh computer is turned on. The sound indicates that diagnostic tests run immediately at startup have found no hardware or fundamental software problems.
But, that may not apply once stepping further into the boot process due to a variety of factors.
Are you getting any beeps or flashes on the power button after the bong?
Can you count the beeps or flashes?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.

If you're sure the RAM is good, try the Hair Dryer trick...

No power light at all...

It can show on any G5, and even many other computers & electronic devices of the period.

I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks
There has never been a reliable firewire ---> USB adapter suitable for external high speed storage. This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
The only high speed port on the Air is the ThunderBolt port. There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options. -
I upgraded to Lion and now Safari hangs up and the updater hangs up so I can't install the update. Can anyone help?
Reinstalling Lion
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alterhatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Continue button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer. -
Just upgraded to the latest iTunes and iPhoto and now cannot change photos on my iPad, can anyone help please?
Try one or more of the following:
> Restart Your Computer
> Uninstall and Reinstall iTunes
> Reset iPod (nothing will get deleted)
> Look in My Computer (Windows 98, XP) OR Computer (Windows Vista or 7) and see if your iPod is in there.
In some cases (and this happened to me before) plug your iPod in and out your computer a few times. It should get it going. If not, then I strongly recommend starting your computer. -

My mac won't recognize an external monitor. The screen Goes Blue Once, then goes blue again and the second monitor just turns off. I am using an HDMI adapter to a visio TV. I also have my xbox on the tv. Can anyone Help??
Lol, figured out the first part. Just for those who may be searching, when you click on the Display Preferences, and click on the arraingment tab... it not only shows where your two screens will be displayed, but the WHITE BAR at the top of one screen is the dock/toolbar. Click and hold to grab this and just slide it over to the screen you'd like it to be on.
You have to release it IN the screen box, not on top of it... and it should pop right over to the new (or old) screen. At any rate, you can put the dock on either (or any) screen that you prefer.
I am thinking of ordering more of these. Lol. 3 monitor setup seems like it would be crazy good.
Still looking for the answer to keeping the new 16" screen on the right without switching between screen #s with that... not expose... Lion feature.
Thanks. Hope my other question has an answer out here.

Hi, I've just installed mavericks but my HPc4180 will not print and is showing a 'blank' page in previews can anyone help me?

go to System Preferences > Printers & Scanners > Print
control-click on your printer in the column on the left
select "Reset Printing System..." and "reset" in the dialog that follows
Do a factory reset on your printer

Please, help!
After upgrading to Yosemite, my dock has disappeared, along with the dashboard and the wallpaper! Can anyone help? I'm using a MacBook Pro, retina, bought it last year.
ThanksHave you been trying to download from the app store? Did you get a message?
As a suggestion, you might go to an Apple store (genius bar appointment) for help. As far as I know, there should be no charge.

I have an IPad 4. After updating the system, when I try to look at picture on Facebook and make it larger, there is just a "circle" in the middle of the page instead of the picture. Can anyone help me?
Close all open apps by double-tapping the home button, then swiping up and off the screen with the app window (not the smaller icon).
Reset your device: hold down the home button along with the sleep/wake button until the screen goes black and you see the Apple, then let go. (No data loss) -

Can anyone help me with this please?have you made sure that the network setting in the system preferences is set up to use dhcp? if not i would try changing it so that it shows that it is getting its address by dhcp

Will I lose my photos in iPhoto if upgrade to a latest version? I have upgraded my system to Mavericks and now my iPhoto doesn't work. Can anyone help, please?
Most Simple Back Up:
Drag the iPhoto Library from your Pictures Folder to another Disk. This will make a copy on that disk.
Slightly more complex: Use an app that will do incremental back ups. This is a very good way to work. The first time you run the back up the app will make a complete copy of the Library. Thereafter it will update the back up with the changes you have made. That makes subsequent back ups much faster. Many of these apps also have scheduling capabilities: So set it up and it will do the back up automatically.
Example of such apps: Chronosync - but there are many others. Search on MacUpdate or the App Store -
