My 27" iMac needs to be unplugged to get it to start after sleeping

Anyone know why I have to unplug my Mac to get it to start up after sleeping

Don't know why this is happening, but first thing to try is an SMC Reset.
Shutdown, unplug the computer, wait ten minutes, hold in the power button for a good five seconds, plug back in.

When I start Firefox, I get msg that it is in "offline mode" and need to "try again" to get online. Started after latest update 10.0.1

When I click onto the Mozilla Firefox icon and open the browser up, it doesn't automatically connect to the online server. Instead, a message appears that it is in offline mode. If I want to go online, I am instructed to click a "Retry" button. This then initiates the online mode.
It doesn't happen all the time but most often first thing in the morning and/or if Firefox has not been opened for a few hours.
Is there something I need to change in the Firefox Preferences under Network/Connection/ Settings?

None of these "fixes" seem apply to Mac OSX10.6.8 . Since I installed the latest update for Firefox I, too, am getting this offline mode and retry message every time I open the browser.
I am not a programmer, so will appreciate a fix I can understand and safely execute to make this terribly annoying message go away.
Work Offline is NOT checked but does appear under the file menu.

My iMac needs to be rebooted every time I put it to sleep

My iMac needs to be rebooted almost every time when I wake it from sleeping. Is this normal? Ether the screen darkens and it will tell me to reboot by holding down the power button or the screen is just totally blank. It's been doing it for a long time and I thought it was just mac security updates running in the backgrownd or something but it seems to be getting worse.
Thanks

Do this:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. 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 installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.

Getting message about having LR5 already open SO I need to know how to get my pictures back-after export.

Hi,
I have been working on photo's and doing the export the laptop freezes up on me, so I have to shut down everything and re-open. When I go to open LR5 back up I get an error message saying that there is LR already open and that I have to open a new folder - Since I have editing all (about 900 pictures) - is there a way of getting those back Instead of having to RE-DO all of them. Which is what I am **** right now and it is VERY hard for me.
I would Love to get a answer on how I can get the photo's back instead of having to re-do all of them again. THIS has happening a few times to me now and I don't like it.
I hope that this makes sense - I would just love an answer..

okay Error message is as follows - pop up window has confirm on the top of
it. The lightroom catalog named "Lightroom 6 Catalog" cannot be opened
because another applications already has it opened. Button Choose a
different catalog, Continue or exit. I have hit all the buttons before and
the ONLY thing that works is to Choose a different catalog and open a new
one?
Might I be able to get my originals photo's back?? the ones that I have
edited already???

IPad 3 needs to be unplugged and re-plugged USB before iTunes will Sync it... Huh?

My iPad 3 needs to be unplugged and re-plugged USB before iTunes will Sync it...
It can be plugged in and online in iTunes, with the home screen showing, and iTunes just hangs when I try to Sync it, unless I unplug and re-plug it USB
Anyone seen this before?

Yes, but I charge my iPad with my iMac, so it's connected most of the time, and to have to unplug/replug it to sync it is nuts.
Why does it hang when I hit "Sync" ? It should never hang. Either I am doing something wrong, or This Is A Bug.

My iMac needs 4 Minutes to start

I don't know why, but my iMac needs 4 Minutes for every start. I have disconnected all USB devices. Can somebody help?

That is one indication the HD may be failing. Before you do ANYTHING else backup the computer!!! If you system came with Lion pre-installed then please carefuly read Hardware Test for instructions on how to run AHD. Run it in Extended Mode, you may need to run it 2-3 times if no errors show up after the first pass. If your machine did not come with Lion pre-installed then refer to your owners manual for instructions on how to run AHT in Extended Mode. If you no longer have the manual click Support in the upper right of this page then click Manuals and navigate to your manual.
Please report back after running AHT with any errors that came up.

Some DVDs not playing in my iMac, need help!

some orginial / genuine DVDs not playing in my iMac, need help!

Once your husband copied the movies, did he use a burn software to burn them to a DVD? You need to use a burn software to properly encode the footage so it'll play in any DVD player/computer/TV. So, once the movie is copied to your hard drive, you can edit it in iMovie (may need a converter first to get it into a format iMovie can work with such as MPEG Streamclip); after you're done in iMovie, use iDVD if you have it or Roxio Toast to burn it to a DVD.
And for the OP: Regions are different depending on where the movie was made: the US, Europe, etc. The regions are set within DVD player - you insert a DVD and the player reads what region it originated in. Please note you can only change regions 5 x; after the 5th, that setting will remain and can't be changed again.

My iMac is home to a 400GB photos library currently syncing to a 500GB iCloud a/c. My 3 MacBooks have much less space which I need and seems to be getting used up fast as it syncs.

My iMac is home to a 400GB photos library currently syncing to a 500GB iCloud a/c.
My 3 MacBooks have much less space which I need and seems to be getting used up fast as it syncs.
How do I reduce the size of the library on the MacBooks - I have already set optimise in preferences but it is using up the space available.
What happens when I download a movie - will it automatically reduce the size of the photos library or am I screwed?

JasonFranks wrote:
OK, had already done all that. My primary concern is whether the system will be fooled by the fact that it will take some time for the 400GB to upload and for the MacBooks to know what volume they are dealing with. It's currently at 100GB after over a day. I guess if it fails I can disconnect from the cloud on the MacBooks and delete the library, right.
If I was transferring data onto the hard drive could it really optimise that quickly?
What is your basis for trusting the magic - have you experienced this?
I've updated my Macs, my wife's Mac, her fathers Mac and my mothers Mac.
It worked everytime, but it takes a while (days or weeks if your library is large)

This answer may be somewhat late, but just in case other have the same issues, I went to site listed below and it solved the problem. No need to reinstall CS5 product. I hope this works for you.

Why do i need to restart my imac everyday like ten times to get it to work, also the screen displays little digital squares.

Why do i need to restart my imac everyday like ten times to get it to work, also the screen displays little digital squares.

Hi Matt,
I purchased my imac in November of 2010 and below is a cut and past from Hardware overview. It has 1 TB hardrive, with 670 GB free. When i start up in the morning, it boots normal then freezes. Half the time i can get it to restart before it freezes, other half i have to power down then restart. At the same time throughout this process the little pixel squares show up sometimes in a single line or two aross the screen, then sometimes more random. After about 7 times of rebooting, everything runs fine for the day with no weird pixels. then i shut down at night, and start the porcess over in the morning. Thanks for your help!

What maintenance does an iMac need (4 yrs old)?

I heard a computer tech guy say iMacs pretty much take care of themselves unlike PCs, but after 4 years of heavy use there must be something to do to keep it in top performance?

How to maintain a Mac
Make two or more backups of all your files
One backup is not enough to be safe. A copy of a backup doesn't count as another backup; all backups must be made directly from the original data.
Keep at least one backup off site at all times in case of disaster. Backing up to a cloud-data service is one way to accomplish this, but don't rely exclusively on such backups.
In fact, don’t rely exclusively on any single backup method, such as Time Machine.
If you get an indication that a backup has failed, don't ignore it.
Keep your software up to date
In the App Store or Software Update preference pane (depending on the OS version), you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis.
Keeping up to date is especially important for complex software that modifies the operating system, such as device drivers. Don't install such modifications unless they're absolutely necessary. Remove them when they are no longer needed. Before installing any Apple update, you must check that all system modifications that you use are compatible. Incompatibility with third-party software is by far the most common cause of difficulties with system updates.
Don't install crapware
...such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, such stuff is useless or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
It's not much of an exaggeration to say that the whole "utility" software industry for the Mac is a fraud on consumers. The most extreme examples are the "CleanMyMac," "TuneUpMyMac," and “MacKeeper” scams, but there are many others.
As a rule, you should avoid software that changes the way other software works. Plugins for Photoshop and similar programs are an obvious exception to this rule. Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction. Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
Only install software that is useful to you, not (as you imagine) to the computer. For example, a word processor is useful for writing. A video editor is useful for making movies. A game is useful for fun. But a "cache cleaner" isn't useful for anything. You didn't buy a computer so you could clean caches.
Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve. Do not rely on "utilities" such as "AppCleaner" and the like that purport to remove software.
Don't install bad, conflicting, or unnecessary fonts
Whenever you install new fonts, use the validation feature of the built-in Font Book application to make sure the fonts aren't defective and don't conflict with each other or with others that you already have. See the built-in help and this support article for instructions.
Deactivate or remove fonts that you don't really need to speed up application launching.
Avoid malware
"Malware" is malicious software that circulates on the Internet. This kind of attack on OS X was once so rare that it was hardly a concern, but it's now increasingly common and dangerous.
There is some built-in protection against malware, but you can’t rely on it—the attackers are always at least one day ahead of the defense. You can’t rely on third-party "anti-virus" products for protection either. What you can rely on is common-sense awareness—not paranoia, which only makes you more vulnerable.
Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must come directly from the developer's website. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from the web, without your having requested it, should go straight into the Trash. A web page that tells you that your computer has a “virus,” or that anything else is wrong with it, is a scam.
In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
Don't fill up your disk or SSD
A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a startup failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem.
While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage use and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
If storage space is running low, use a tool such as OmniDiskSweeper to explore the volume and find out what's taking up the most space. Move seldom-used large files to secondary storage.
Relax, don’t do it
Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
To use a Mac effectively, you have to free yourself from the Windows mindset that every computer needs regular downtime for maintenance such as "defragging" and "registry cleaning." Those concepts do not apply to the Mac platform.
A well-designed computing device is not something you should have to think about much. It should be an almost transparent medium through which you communicate, work, and play. If you want a machine that needs a lot of attention just to keep going, use a PC, or collect antique cars.
The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.
