Hello, I have iMAC 7,1, 20 inch,
4gigs of ram,
Intel C2D
ATI Radeon HD 2600 Pro 256 MB
HDD 320gig's
iMAC is perfectly runing OS Mavericks (10.9.5), with no lag, and no sluggish working, Multitasking is AWESOME (i have PC, with 8gigs of RAM, GeForce GTX570, etc etc), but i must say this MAC is running way better a way way, faster and I am Loving it!!! I am using it for making music, and video editing, i am Using Final Cut Pro x, Ableton 9, Logic Pro x, and bunch of other apps and it is working perfectly, and i am so shocked how machine old like this can do that stuff better than any PC i had, and not to mention that I use more time on iMAC than on PC, i use Windows PC just for occasional gaming, but that is like 10% of time, so i use my MAC in 90% of time.
So, enough of my iMAC. I am wondering if I update it to Yosemite, will my iMac slow down, and not continue to work like on Mavericks? Will it become sluggish and unresponsive? Will it affect reliability and stability which have on Mavericks? And will update delete my personal data (tons of Logic, Ableton and Garage band projects, and tons of Final Cut Pro projects), Applications (because I have some apps which is hard to find these days)...
I know bunch of you guys would tell me to backup my data, but i don't have External hard drive (they are pretty expensive in my Country), I have some friend who could borrow me External HDD, but they have their data on it, and they mostly use windows.. I did not use Time Machine yet, but i think probably it would format HDD on Macs partitions, so, i will do it on my own guys (don't judge me about that guys please)..
So if someone could answer me that, i will really appreciate that.
Thank you, and best Regards!!

I recommend you upgrade your RAM to at least 8 GB for good performance with the apps you're using. Also keep a minimum of 25-30 GB of free space on your boot drive for optimal system and application performance.
The maximum RAM a 7.1 iMac can address is 6GB, the OP can keep one of the 2GB DIMMs and then add a matching 4GB DIMM. If the OP decides to do this, please only purchase from Crucial or OWC at www.MacSales.com.
However as described on a 8 year old iMac, I'd stay with Mavericks and then when considering upgrading upgrade to a more up-to-date Mac.

Hello, I have iMac Itel i3, from Oct, 2010 and have OS 10.6.7 and multiple users.
About 3-4 days ago the Mail icon in dock had question mark and was accidently removed, along with program on my user. Oops.
1. Mail 4.4 is on other users and works fine, but for me it does not work and tells me V4.3 does not work with latest OS X.
2. I reloaded software from my user with original disks (Oct, 2010) and got Mail 4.3 again. Mail 4.3 did not work with latest OS. I am unable to load Mail. Gives Yellow error message.
" You have Mail version 4.3 (1081/1084). It can’t be used on Mac OS X Version 10.6.7 (Build 10J869). For more information, click the Help button."
3. Tried to update software and look for update for mail 4.3 on Apple site to no success.
Hate to go to MS-Entorage ( I may need to learn something new and alien) mail program since contracts are in Mail/Address Book.
Ideas?
MattDeedsMatt,
I would download and run the 10.6.7 combo update.

Hi, I have a macbook pro 17" 2.4ghz intel core 2 duo 2007, will upgrading to Yosemite slow me down or create problems with my Iphone or other app ?
Yes, i do not suggest upgrading right now. There is some software malfunction or glitch that spontaneously shuts down this specific model. I upgraded and it was a pain to downgrade and make my mac usable again.

I have Firefox add on's such as Weather-bug and Reminder. I want to know if these add on's can slow down my computer. They seem to be doing that. And, if I need to delete these add-on's from my computer. How would I go about doing that?
Thank You,
Gary W. LusterJust to the right of your post, you should see an "Edit this post" link. Click that, and then next to the subject text just above the message text edit box, you should see an "edit" link. Use that to remove your email address.
To remove an add-on, go to the Add-ons menu item. In Firefox 4 that's on the FireFox menu (upper left corner of the window). In older versions it's on the Tools menu. Then you want to choose the Extensions tab, and find the add-on you want to remove. It should have a Remove button next to it. -

Really frustrating. I have tried to pair 2 different remotes to see if that was the problem, but still can't toggle but up or down........ help!!
Have you restarted the AppleTV?
I have several white remotes for ATV1's and a couple have 'sticky' up buttons that require a harder press (one of these was chucked in the sunk a few years ago by my daughter), so I'm not convinced of their longevity as much as I prefer them ergonomically over the new silver ones.
Odd for two to be exhibiting the same issue which which is why I suggest restarting. If you had a low battery you'd probably be getting an onscreen warning icon. -
Windows 7 Pro on iMac (mid 2011) and network slows down
We have an office with about 8 mid 2011 21" iMacs running Windows 7 Pro courtesy of Bootcamp. The machines boot quickly and all programs open quickly. They each have from 2 - 4 mapped network drives to a 2012 Windows Server 2008 R2 HP GL380 server on-site and are wired with Gig Ethernet HP business class switches). The users' Documents, Desktop, and a couple other directories are re-directed to the file server using an Active Directory Group Policy Object (GPO).
A couple of the computers will regularly start to slow down after only 20 or 30 minutes of use. The rest have occasionally experienced it but it's always independent of others experiencing the slowdown. The computers with the more regular slowdowns I've also booted into OS 10.7.x and the transfer rates to the same file server are fast and consistent. BTW, all computers are current on Windows updates and Apple updates.
I've tried some of the suggestions I found here: http://www.neowin.net/forum/topic/950538-running-windows-7-via-bootcamp-on-mac-m ini-slows-down-over-time/
1.)
Disable all property's that has something to do with "Offload" under advanced on the nic properties.
Also disable "Recieve Side Scaling".
And set "Speed and Duplex" to auto.
2.)
Turn off windows feature "Remote Differential Compression" (Uninstall) under "programs and features".
3.)
Run fallowing command in cmd:
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global chimney=disabled
i ran disabled on every setting i could.
so it looks like this now:
C:\Users\tab>netsh int tcp show global

Chimney Offload State : disabled
NetDMA State : disabled
Direct Cache Acess (DCA) : disabled

4.)
Uncheck fallowing under your local area connection properties:

Link Layer Responder.

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.

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. -
