my computer is not acting wierdly or anything, it has the same temperatures it has had since i bought it, i just thought maybe a clean should be good
THX IN ADVANCE FOR YOUR HELP!!!

Please describe exactly what you mean by "not recognizing the network".
It's common to have to reset a modem to convince it to connect to a new device, such as your Time Capsule. The method for reseting a modem varies with the modem.
You should install AirPort Utility on your computer so that you can configure the Time Capsule.

I have a previously installed app's mobileme sync pref. still in my mobileme sync list in system prefs. Any suggestions on how to remove this?

I have a previously installed app's mobileme sync pref(com.panic.transmit.Favorites) still in my mobileme sync list in system prefs. Any suggestions on how to remove this?

Thanks again for the idea. I just tried it and it didn't work... sort of. iTunes is syncing the photos because I can see that it's optimizing them and syncing them without crashing. Then it says that my iPhone sync is complete and I can safely remove iPhone. But again, when I go into the Camera/Photos app nothing. When I bring up the camera and then touch the the little double square icon on the bottom left the only thing that comes up is a title at the top that says Camera Roll. Then in the middle of the screen is a big icon of a camera and the words No Photos under that. There's no way for me to go to a list of my iPhoto albums. UGH! What's up with this?

Clean installation of system 7.1 on Macintosh SE/30 ?

Could someone please advise how to do a clean installation of System 7.1 on my old Macintosh SE/30 ?
It used to run 6.0.5, I have done an upgrade to 7.1 , but I think I have somehow messed it up.
For instance , the Apple menu is empty.
It still boots fine, and I can read floppies.
I did google a bit, but didn't find any step-by-step instructions how to do the clean installation.
I've got the floppies Install 1 & 2, Tidbits, Printing, Fonts, Disk Tools.
Could some kind soul please advise?
(I've got Macbook's , but I am not really familiar with the vintage Macintoshes.)

Would it be correct to assume that you have the (more common) 1.44 MB System 7.1 floppies (HD diskettes)?
If you do not wish to keep anything of the existing hard disk contents (and if you have backup copies of systems and applications that you want to install), you could simply boot the computer from a Disk Tools floppy and then use Apple HD SC Setup to initialise (format/erase) an Apple hard drive. If the internal hard drive is not an original Apple drive, or if an Apple drive had been reformatted by another program, a modified/special startup floppy with a third-party formatting utility would be needed instead. Thereafter, start up from the System 7.1 Install 1 disk and carry out a fresh installation.
BTW, the floppy drive is first in the boot order, so a Macintosh SE/30 should start from a (bootable) diskette even if the hard disk contains a system. If there is a problem doing this, one can try holding down the four keys Command(Apple) + Option + Shift + Delete(Backspace).
Since old system floppies become unstable with time, it is a good idea to create a set of sector-copied backup disks. The typical application for this would be Disk Copy 4.2. This program was earlier available from Apple, but the older software downloads list is not there any more. A Disk Copy 6.3.3 page can still be found, though.

Clean up cooling system - do it yourself or give it to service

Hi,
I'm a happy owner of X200 for a year. Recently the cooling fan started turning on more often - it's time to clean the cooling system. My question is - will I loose warranty if it do it myself ? (disassembly laptop, put new cooling paste, clean the dust) Maybe I should give it to service? Any people experienced in this topic?
Has anyone disassembled his X200 to do these things? Is it very complicated compared to other laptops?
Thank you for answers in advance,
Kind regards,
Lukasz

if you take out the heatsink/fan then there is a good chance that your warranty maybe voided. If cleaning the vane of the fans and wiping off any dusts don't work, then just send it in, and the depot will change a new fan/heatsink for you.

Clean up the system

I have been using Archlinux for almost a year now. I started to notice that my root filesystem size has been increasing. It now stays at 6GB. I wanted to know if there are any ways of cleaning up the system of leftover files.
I asked in irc and read in newsletter about pacman -Qdt and removed all orphan files. I still cant believe 6GB has been filled. Is it possible for pacman to list the packages in the order of decreasing size?
Have anybody faced a problem like this ? What should be the approach to cleanup the sytem?

sense wrote:That cleaned up 300MB. It seems I have installed a *lot* of packages. Can pacman output the packages in the order of decreasing size?
pacman can't, but there are many ways to do it. A simple script using pacman, or using directly /var/lib/pacman, or a tool using libalpm.

My newest iMac from a year ago is showing signs of slowing down its processing capability. Notice it especially in Aperture where I get the whirling dervish thing sometimes for a minute or more and once it crashed. Is there a way to "clean up the system"?

My newest iMac from a year ago is getting very sluggish. I notice it particularly in Aperture. I get the whirling dervish thing going on an operation sometimes for many seconds, even a minute or more and once it just crashed and I had to restart with the button. So I'm wondering if there is some way to "clean up the system" that is built into the iMac or if there is a reliable app I can obtain that will clean things up. I'm supposed to have a super fast processor in this version of iMac and lots of hard drive space and RAM. What gives? Any suggestions?

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X 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.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
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, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
          Mac OS X Snow Leopard and malware detection
          OS X Lion- Protect your Mac from malware
          OS X Mountain Lion- Protect your Mac from malware
          About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Why can't I open pdf's after install of adobe reader? Should I see it in system preferences?

Why can't I open pdf's after install of adobe reader? Should I see it in system preferences?

There are can be reasons PDFs cannot be opened. For example, some forms created with Lifecycle Designer cannot be opened.
Are you sure the file is a PDF? Can you open it in Adobe Reader or Acrobat on a Mac or PC? Does it give an error message when you try to open it?

MacJanitor - apps to clean up my system

Hi,
Before I used an app called MacJanitor, which cleaned up my system my iBook wasn't left on continuously. Since installing Leopard I have tried using it and it doesn't seem to be doing much - pretty much saying "Done" as soon as I run it. I wasn't sure if this was something to do with Leopard i.e. MacJanitor doesn't work with it? Alternatively, does anyone know of a similar app that work with Leopard?
Thanks in advance.

Thank you Yann.
I read your link to A Brody's warning about corrupted cache files -
http://discussions.apple.com/thread.jspa?threadID=1322708&tstart=0
On my new iMac I installed The Sims 2.
Now my iMac behaves in all sorts of weird manners. For instance:
+i) Input and dialogue boxes now have a dark border line around them when clicked on;+
+ii) clicking on folders, opening windows and all other mouse actions now have amusing sound effects attached to them (I assume they came from the Sims 2 game);+
+iii) the 'Apple Menu' of my intel 24" 2.8ghz iMac now displays two versions of each option Sleep, Restart and Shutdown (with the Keyboard shortcut displayed for each being different and distinct - which is itself odd) amongst others. Open, Close etc. are ok, just the one as normal.+
I followed the game producer's detailed instructions to remove all items I could find associated with The Sims 2 (they told me what to look for) and trash everything. Annoyingly the problem nevertheless persists.
I read this thread because I thought of using MacJanitor to clear my cache files +(I turn all electrical stuff off at night)+ as a possible way to solve my problem. After reading *a brody*'s comments I now wonder if my own problems could be due to a corrupted cache file instead.
The reason I say this is because it only occurs in one of my four 'User Accounts', and not in my Administrator's Account.
The User account in question was 'migrated' from my eMac which has been suffering from kernel panics and has been down now for some time with me scratching my head in desperation.
I'm beginning to think that it was a mistake to migrate all my eMacs settings over to my new iMac.
Assuming all this being the case, I wonder if running Disk Warrior (or TechTool Pro 4) to fix the corrupted system cache files would work, especially as the most severe problems have occurred since installing The Sims 2 game.
I am assuming of course there is a version of these programmes available for my operating system - OSX 10.5.1 - Leopard. Both programmes resurrected my eMac to get it going but the kernal panics return nevertheless and the fault with this persist. However if a corrupted cache file is the cause not just a symptom I may be able to kill two birds with one stone!
WHAT HAPPENS IF ONE DELETES THE OFFENDING USER ACCOUNT. Can this be done? If so, what is the best way to do this to avoid data loss?

Any recommendations on how to do a clean install of Win 7 Pro OA?

Hey Guys, I just got my new x201 and I'm looking to do a clean install of windows 7 pro (oa)
any ideas on how to do it without using the rescue and recovery? im trying to avoid all the factory programs being installed, so i dont want to use the rescue and recovery option. my main concern is activation, but im also wondering what CD/DVD i would use to install the OEM/OA version since it didnt come with any media. does lenovo provide this if i need? i can already see performance decrease in some applications, and in just general use of the computer. any help would be GREATLY appreciated.
i was also wondering if it would be a big deal if i got an SSD for this laptop, would thre be any activation issues with the OEM/OA version?
thanks in advance
nick

Another note Rescue and Recovery can create OS only disks instead of just factory reset and can also create as is which copies exactly how the PC is now. Not sure why no one on this forum knows that or atleast does not tell anyone. weird. Those options are under the create disks tab. Great for like what your needing to do. Install all the programs and make the as is disk to put on all 99 other PCs. Cheers! EDIT note: Nevermind my useless info posted above. I just confused R&R with OKR AGAIN. Does someone know how to use R&R that could post info. Can R&R create disks of the system as is like OKR can?
