Can anyone help with clearing space on my Mac Mini, it says the hard drive is full and runs slowly.

Please help, we got the Mac Mini from a family member so it may have his stuff on it but no longer required, we have only put a smal amount of data on it so don't believe we have over filled it. I backed up to a hard drive all photos etc as I thought it may be them filling it, now I cannot even scan a document to it. Is there any way to Defrag it as you can normally do to a windows system as well as either declutter it or restore the whole thing.
Best Regards
Smithy

The first thing to do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. You — not the previous owner — must do that. How you do it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
1. You don't own another Mac.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. For early MBA models, you may need a USB optical drive or Remote Disc. You should have received the media from the previous owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
2. You do own another Mac.
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to create a bootable USB device and boot the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can boot from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
Once booted in Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
After partitioning, quit Disk Utility and run the OS X Installer. You will need the Apple ID and password that you used to upgrade. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
Then run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.

I have a new Mac Mini. When I start it, the message and mail program's open automatically. How do I change this?

When I boot up my Mac Mini, the mail and message program's open automatically. How do I stop this?
I heard that all program's that are open when shutting down, will open again on booting up. I always close all program's before shutting down!

Go to preferences and General and be sure the box is checked that states to close all programs on exit. Also, right clcik your mail icon in the dock and under options be sure the open at login is not checked.

Mac Mini Won't Sleep after installing 10.4.6

My Mac Mini wakes itself up after just 1 minute of putting it to sleep mode. I've tried restarting my mini, and tried quitting all apps and disabling airport and bluetooth- but it still won't sleep! Anyone else experiencing this problem, I didn't have this problem with 10.4.5 and I've installed no other software since then...

This is for a Mac that won't sleep.
First, read things in Apple doc.#25801 on sleep settings.
USB devices and hubs often cause Macs to not sleep or wake quickly from sleep (notably HP printers and scanners, HP all in ones, and Cannon scanners). Disconnect all USB except for keyboard and mouse and try. If it sleeps, add one back at a time testing after each one to find the culprit.
If you've set your Mac to recieve faxes, it may not be able to sleep. It might also have a damaged preferences file.
If you use your Mac for faxing, open System Preferences. click Print & Fax, click the Faxing tab, and uncheck the Recieve Faxes On This Computer box.
If that does'nt work or you've never faxed on your Mac, go to Finder/Hard Drive /Library/Preferences/SystemConfiguration and delete the com.apple.PowerManagement.plist and com..apple.AutoWake.plist files (if your Mac asks, type your admin. password).
If the latter file isn't present in the folder, go to user name(probably your name)/Library/Preferences, delete the com.apple.systemuiserver.plist file, and reboot your Mac.
Hope this helps!
P.S. One member here reported this (Michael Gleason);
"I have had this problem with my IMac G5. It is surprisingly irritating. LaCie's Silverkeeper backup software was the cause. By default it gave itself permission to wake up the computer to check if a backup was needed. Do you have this or a similar program installed which has scheduled activities including wake-up permissions as an option?"
Dave Hamilton provided this link, xlr8yourmac.com, to a member, which addresses failure of deep sleep with some users that updated and added new FireWire and USB cards.
tomhorvat adds this; After few days of messing around I found out that I had desktop background (wallpaper) set to change every 1 minute.
After unchecking "Change picture..." in system preferences (under Desktop/Screen saver), my powerbook went to sleep all by itself.
Cheers!

Mac Mini won't start after installing OS X 10.6.3

My Mac Mini won't start after installing Mac OS X Snow Leopard 10.6.3. When I turn it on, the Apple logo appears and the initialization line starts to fill, but it suddenly stops. It does that again and stops at the same point, but this time it shuts down. What should I do?

If you are coming from 10.5.8, hopefully you backed up your important data first. Your mini will need at minimum, 1 GB of RAM to install Snow Leopard and at least 5 GB of storage remaining on your boot drive.
I treat 10.6.3 as a fresh, full install over a 10.5.8 system. That means I choose Disk Utility from the Installer's menu and repartition the boot drive as a single partition, Mac OS X Extended (Journaled) format, and use the GUID partition scheme from the options button. At this point, while still in Disk Utility, I would verify the drive under First Aid.
Then I turn the installer loose, and reboot into a working 10.6.3 system, ready for the software updates that take the machine to 10.6.8.
So, following the above guidelines, reinstall 10.6.3.

My mac mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone

My Mac Mini does not boot, after backing the enire system onto an external drive with Carbon Copy Clone. I had switched the start-up disk back to the original of course. Now all I see is the Apple logo. What should I do? Thanks in advance.

Try disconnecting any external devices, especially hard drives
and try rebooting.
If that doesn't help, then :
If you are running Lion, boot to the Recovery HD and run a
Repair Disk on the OSX partition.
If Snow Leopard, boot to the installl DVD and run Repair Disk.

MAC Mini does not restart after Yosemite update

I bought my MAC mini in 2011 and I successfully updated to Mavericks with no problems. I am not sure why my MAC Mini will not restart after I updated to Yosemite. The completion bar gets stuck around 30%.
Any help or ideas appreciated
Larry

Okay, this is strange. I tried restarting three times yesterday with the same results. In fact I left it go overnight only to find the next morning that the bar was still stuck at 30%. I did a hard boot a little bit ago and waited a few seconds. I restarted an it booted up fine.

Does Mac Mini require power adapter for European voltage?

Does mac mini require a power adapter to safely operate on European voltage?

Thanks Anamusic! Since my other Apple products have the square adapters (iPhone, iPad, macbook) it seemed strange only to have a plug cord for mini. don't want to fry it over here in Europe.
You only will need a new Duckhead US-Plug-Type C (2 pin Europlug) for your MagSafe power adaptor. See picture below.
All Apple MagSafe adaptors are mulitivoltage devices and support AC 100V to 240V
All Mac's with build in power supply (like iMac) have also multivoltage units.
Mac Mini uses (depending on production year) different power units, Mac Mini 2011 have a internal power supply, but ALL are "multivoltage".
So you just have to change the cord or use a adaptor.
The above adaptor is suitable for use with Apple's laptop power adapters, and some other products e.g. some iPod, iPhone, iPad adapters. It will however not fit the Mac mini of any generation.
Also, only the MacBook, MacBook Pro, and MacBook Air have the Mag Safe connector which is at the laptop end of the cable. The picture you posted is for the wall socket end of the cable. Older Mac mini computers use a proprietary connector, the 2010 and 2011 models use a standard IEC C7 connector.

Mac Mini won't boot after wind storm flickered lights

My Mac Mini running OS X 10.5 will start up but won't go beyond the Apple logo.
I can't even get it to start in Safe Mode. Is there any way around this problem besides
buying a new computer?

Usually, if there is a power disruption (or a static shock to the computer) and it does
not work correctly, you may be able to perform a power management unit re-set;
if the computer is a G4 PPC Mac Mini, that would be a PMU reset. If the computer
happens to be a later Intel-based Mac Mini, the procedure would be an SMC reset
and different rules would apply. I have added links to both methods in this post.
There is a chance some hardware damages may have occurred to the computer due
to being unprotected and not isolated from grid power fluctuations; such as provided
by use of an 'uninterruptible power supply' or 'backup power supply' which would be
able to switch to battery backup automatically when the main power goes haywire.
Which model Mini do you have? Since I have a G4 PowerPC Mini, I know something
about resetting Power Management Unit procedures since I've notice the Mini is more
likely to need a reset due to static shock when normally touching the computer; with
winter weather and less indoor humidity. (Otherwise, I have UPS power protection.)
Links to both kinds of power/system management reset procedure are below.
• PPC-based G4 Mac Mini: How to reset the PMU
http://support.apple.com/kb/HT2183
• *Intel-based Macs:* Resetting the System Management Controller (SMC)
http://support.apple.com/kb/HT3964 (mini reset instructions, as follows)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Press and hold the power button for 5 seconds.
4. Release the power button.
5. Attach the computers power cable.
6. Press the power button to turn on the computer.
{You may wish to read through the entire Intel-based Mac article if your Mini
is of this architecture, since there may be applicable hints for all Intel-Macs.}
Not sure about your other continuing issues; I'd have to re-read the posts,
since I have been interrupted three times during this post, locally...
If the computer does run, eventually, it may be some directory damages or
other sector or data errors have occurred in the computer's hard disk drive;
and you may have to consider buying Disk Warrior on disc so you can boot
the computer from its disc to repair the Directory on the hard disk drive.
Restoring is easier if you should have a complete clone of the computer on
an external hard disk drive; one that is capable of booting the computer.
Good luck & happy computing!

i have a mac mini mid 2011, this device have; 2,3GHz and 2 Gb Memmory.I want to upgrade the memory and i need the list of supported memory modules. i am from turkey.

Welcome to Apple Support Communities
The Mid 2011 Mac mini supports 8 GB of memory officially, but you can install up to 16 GB of RAM, so you can use 2, 4 and 8 GB modules. You can buy more RAM from OWC or Crucial.
If you are looking for memory at a local shop, make sure you buy 1333 MHz DDR3 memory. See > http://support.apple.com/kb/HT4432?viewlocale=en_US&locale=en_US

I run a Mac Mini 10.6.1 and a G5 10.4.11 - they share a screen. Yesterday the contrast on the Mac Mini went mad. Very very heavy contrast and now its impossible to retouch with Photoshop as I cannot judge the colours accuratly. The G5 is fine. I keep the screen image I get on the G5 good and accurate with Huey. I believe I cannot use this with the "Intel Inside" Mac Mini. Does anyone know how I can restore the great screen image I got up to yesterday on my Mac Mini? Thanks. John Suffolk England.

Likely caused by one of the following: a bad cable, maybe a bad connection or (my guess) bad graphics hardware.
To rule out the software, see if booting from an installer DVD shows better color.
Swap the cables and check the connections.
Then call your hardware support provider.

My Mac Mini (Mid 2011) doesn't connect to Time Capsule in 5GHz Network. This WiFi Network don't appear in the WiFi list. What's Wrong?

My Mac Mini (Mid 2011) doesn't connect to Time Capsule in 5GHz Network. This WiFi Network don't appear in the WiFi list. What's Wrong?

Oh yes, & 5 GHz doesn't do walls very well at all.
GHz and Network Range
The higher the frequency of a wireless signal, the shorter its range. Thus, 2.4 GHz networks cover a substantially larger range than 5 GHz wireless networks. In particular, the higher frequency wireless signals of 5 GHz networks do not penetrate solid objects nearly as well as do 2.4 GHz signals, limiting their reach inside homes.
