Autocad work on mac os lion is slower compared to window

i use auto cad on a daily bases. i also use cad on windows system. on mac the cad works a little a slower. mostly in zoom and pan command.

I cross posted this and now it won't let me delete this post. So I will just say that this is resolved. I had to right click on the .htaccess file and remove the .txt from the get info box. It then started working. The .txt wasn't appended to the .htaccess from the file browser as it was hidden. Caused me some grief.

Why is mountain lion so slow compared to snow leopard?

Just installed Mountain Lion from Snow Leopard (skipped Lion).   I like the features of Mountain Lion but it is incredibly slow in overal start-up and general system responsiveness compared to Snow Leopard.
Running iMac and Macbook Pro and both are the same in really slow performance.

OK, been a busy week but I've installed RAM.
Had iMac 2007 model (iMac7,1) with 2GB of RAM (two 1GB modules).   Upgraded recently to 6GB of RAM (one 2GB and one 4GB module), yes, I know this is above the original specs of 4GB, but this model does indeed support 6GB with Snow Leopard or newer.   This now works fine under Mountain Lion with no spinning multi-colored ball.   With a couple of applications like Safari and Mail open, it has (using Activity Monitor) just under 2GB free memory.   Page Outs are now a very small (close to zero) fraction of Page Ins.   So, it works well.     If you are not upgrading memory then stick to Snow Leopard as it is a much lower memory footprint.
Had Macbook Pro 2008 model (MacBookPro5,1) with 4GB of RAM (two 2GB modules).   This wasn't performing as bad as the iMac with Mountain Lion but was still slow.   Anyway, upgraded to 8GB of RAM (two 4GB modules).   This is also now working fine with no major issues observed.
If running VMWare fusion, then a lot of the memory will be used up.   The free memory is very slim on on an iMac when running VMware Fusion with MS Win XP (ugh!), which I only do for a couple of scientific antenna analysis programs that I like to use that just aren't available on the Mac, but it is workable. Occasional memory address messages appear from the guest OS but othrwise fine.
So, in summary, if you have older machines (with low RAM) or have a multitude of apps open then Mountain Lion requires careful consideration as it needs just over 4GB when a couple of memory hungry apps open. Do anything exciting andmemory usage will increase causing tons of Page Ins compared to Page Outs and you'll be running in slow virtual memory.   So, for machines that you won't upgrade in RAM stick to Snow Leopard.   For modern Macs with 8GB, 16GB or more, then all will work well.
I still wish they could make the memory footprint leaner though.

How difficult is it to load software on to a Mac running Lion that was written for Windows Xp,Vista. Can it be done without causing major issues.

I am interested in getting a medical simulation program but it is available for Windows only. Is it possible to run it on a Mac system?

You'll need to buy:
- a Windows emulator for Mac
- a version of Windows to run in the emulator
I dimly remember putting that stuff on my wife's computer several years ago & it's been fine.
Google: windows emulator macintosh
Macs used to come with their own Windows emulator, but you had to log off one OS & log on to the other one. Flipping back & forth was not good. A better approach allows you to flip between OSs like flipping between applications.
I seriously down if you can still buy Windows XP. Stay away from Vista. Windows 8 gets good press.

What version of photoshop works with Mac Mountain Lion?

I have an older Mac. Upgraded to Mountain Lion. Installed CS3. All works fine but for photoshop. Is there a fix? Or is there a version of photoshop that will work with ML that I can purchase?

Moving this discussion to the Photoshop General Discussion forum.
Jim Sloan do you receive a specific error when trying to use Photoshop CS3 under Mac OS 10.8?
If you are looking for a version of Photoshop designed for Mac OS 10.7 and later then I would recommend Photoshop CC. There a couple different options to subscribe at the moment. You can find more details at https://creative.adobe.com/plans/offer/photoshop+lightroom?promoid=KHQFP and https://www.adobe.com/products/creativecloud/buying-guide-at-a-glance.html. Please be aware that the Photoshop Lightroom Photography bundle is only available for a limited time.

HP 7310 scanner doesn't work with Mac Mountain Lion

I just tried to scan a photo on my 7310 Officejet All-in-one. It tells me I need to install software for this feature. I know I scanned a photo with this same setup before. However I upgraded to Mountain Lion and now it's not working. I tried to find a download but the HP site tells me all my printer downloads are installed. How do I get the scanner to work? If this is a common problem for people using Mountain Lion why not just create a download for all of us to run? Or a patch perhaps? Thanks for your help.

sc00ba,
I am sorry you are having the issue with your software.
1.) Did you uninstall the software before attempting to reinstall it?
2.) Have you looked at this document to assist in the installation?

Does Logic studio works on Mac OSx Lion?

my Mac Could not read my install dvd Logic studio disc in lion. Why? Please reply
current mac version: 10.7 ( mac Os x Lion )

thank you for your kind reply.
what puzzled me is this...
1. i have 2 mac, 1 is the white mac & the other is mac pro which i newly bought
2. as for the white mac is my previous mac which i have upgraded to run on Lion
my mac pro could read the logic dvd but strangely not my white mac.
but my white mac could read other dvds;
so as to DVD scratched, i'm scratching my head as to what is the problem.
so how should progress from here?

Which Sprint broadband cards work with Mac OSX Lion?

My company uses Sprint and when I upgraded to Lion, my Ovation U760 broadband modem was no longer supported. I can't find any Sprint cards on their webpage which indicate they work with Lion.

Well, you can try to shame us if you want, but the discussions I heard
around me was that it was more important to deliver cross-platform mobile
development when we did than to wait and divert energy and time to
certifying on a new OS version, and potentially wait for a new Eclipse
version before we could do that certification. Everything under us keeps
changing and we have to pick a point in time and ship. Then we start
upgrading and certifying on later stuff. We are in the process of
certifying on Lion.

Why does my mac transfer files so slow compared to a PC?

I am not very good at computers, but i noticed that my friend's computer (a PC) transfers files way faster than mine, and i don't think has better hardware than me. when i transfer files to a flash drive it takes around 30 mins to fully transfer 8 gigs of files, and his PC takes half the time. any ideas why his computer transfer files faster? can some one tell me what might be the difference between his PC and my MacBook Pro
My MacBook Pro has:
Processor: 2.3 GHz Intel Core i7
Memory: 8 GB 1333 MHz DDR3
Hard Drive: 750.16 TOSHIBA MK755MGSXF Media

30 mins. for 8 GB seems too long even for USB 2.0. If the flash drive is working at 60 MB/sec., the max speed for USB 2.0, it should take about 2.5 minutes to transfer the whole contents.
It may be slower because there are other USB peripherals on your Mac's USB bus...printer/scanner, display card, etc.?
USB flash memory has a format, just like a drive. Perhaps you'd get faster performance if you formatted the USB stick in the Apple format; (but I can't imagine that's the cause) or there's some other hangup with that hardware. Try another USB stick. If you buy a new one, insert it into the Mac, but before using it, go to Disk Utility and format it as Mac Extended.

Inbuilt speakers are not working in mac os X 10.5.2 or Windows

{ During startup, inbuilt speakers work and give startup sound but as soon as any of the OS loads, sound via inbuilt mac speakers doesn't come out...

JTable scrolling in Windows 7 very slow compared to Windows XP

I am running the following test program on jdk-6u18. The program displays a simple 900 rows x 20 columns table with each cell being an integer 1. When I run this is Windows 7, the scrollbar handle cannot keep up with the mouse movement as I drag it up and down. But the scrolling is very smooth if I run it on a Windows XP virtual machine on the same PC. Is there any way to improve the JTable performance on Windows 7?
Thanks.

Is there a way to get PSE to work with my scanner in Mac OS Lion

I recently baught a new Mac mini. So, now I must work in Mac OS Lion. However, I can't seem to get Photoshop Elements to work with my Epson Stylus CX5000 all-in-one. I am beginning to get the impression that Adobe has not provided an intel based Mac OS plugin to allow their applications to directly access scanners. Is this the case? If so, what can I do to get PSE to access my scanner?

Try Vue Scan 9 which is designed to run old hardware on a new OS or third party applications. There is a free trial.

Mdworker process - mac is very very slow, apps not responding

A couple of days a ago, I noticed there was lots of chatter coming from the hard drive. I also noticed that the Mac Pro was very slow at doing most things, lots of beach balls and applications not responding. Right now, all I can hear is the HDD
I opened up activity monitor and noticed that a process name called - mdworker - was using 8.83GB or Real Mem and around 11.80GB of Virtual Mem. These figures fluctuate, the Virtual Mem has gone as high as 14GB. Sometimes the process goes down very low to say below a GB, then rises again.
I have 10GB of ram installed inside the mac. Furthermore, I've seen 100%of CPU use though mdworker.
I've been reading about this problem, lots of advice says to move the HDD image to the privacy pane on spotlight as this is a indexing/spotlight issue, though I still want to use spotlight.
Will this process ever end, or is there a way to stop it, as is using up all the resources?
The only thing I've installed of late is a music plug-in called Geist and an expansion pack which came with it.
Right now I can't rally use my mac like before, I'm writing this on an iPad.
Any help would be great, as the mac is integeral part of m work.

the Mac Pro was very slow at doing most things, lots of beach balls and applications not responding.
How much free drive space on the Mac?
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space.
You can stop Spotlight from indexing > Spotlight tips
Have you emptied the Safari cache lately? From your Safari menu bar click Safari > Empty Cache. Quit then relaunch Safari to test.
If that didn't help, back to the menu bar, click Safari > Reset Safari. Select the top 5 boxes, click Reset. Try Safari.
And try troubleshooting the Safari .plist file (preferences)
Go to ~/Library/Preferences
Move the com.apple.Safari.plist file from the Preferences folder to the Desktop.
Quit, relaunch Safari to test.
If that helped, move the .plist file to the Trash, If not, just move it back to the Preferences folder.
And try troubleshooting Safari third party plugins. Go to Safari > Preferences then select the Security tab. Deslect: Enable plug-ins
Quit then relaunch Safari to test. If that made a difference, then you need to find the plugin(s) causing the problem > Unsupported third-party add-ons may cause Safari to unexpectedly quit or have performance issues

My mac OSX lion is now very slow, any idea why?

my mac OSX lion is now very slow, any idea why?

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 a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion/Mountain 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.
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.
Repair the Hard Drive - Lion/Mountain Lion
Boot from your Lion Recovery HD. 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.
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. 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 and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X 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.
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 Lion 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. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency 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. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
Get an external Firewire 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. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or 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:
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, 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.

After downloading OS X Mountain Lion, my mac has become very slow

After downloading OS X Mountain Lion, my mac has become very slow and takes a bit to shut down programmes. What can i do to bring it back up to the speed it was when i had OS X Lion

Though I wish it were true, it is unrealistic to put 200+ new features into OS X and expect Mountain Lion to run faster and more efficient than Lion on the same hardware. I moved up from Lion to Mountain Lion. Mine is slowing down, but not very slow, as you mentioned. Safari and Mail are simply swine on launch. Check the following:
Patience. If you are impatient and detail alters your mood, take your MBP to the Apple Genius bar.
CPU. If you have a supported, but older MBP, your CPU may be showing its age.
Memory. 4GB or 8GB in your MBP? Mountain Lion drinks more than Lion and if you run multiple large memory footprint applications, 4GB will be a performance bottleneck. My HD3000 graphics takes 512MB. Check the System Information report for your memory. Is it OK?
Compatibility. Sometimes, hardware peripherals and applications are not entirely compatible with a new OS release, and divert OS performance to system log entries. A symptom is a large (> 2GB) system log file at /var/log/system.log. I just discovered a bad USB hub this way. Unplug everything and evaluate your performance again. Zero [ # > /var/log/system.log] the log file if you have the permissions.
Permissions. Launch Disk Utility and verify/repair Disk Permissions on your Mountain Lion disk. While there, might as well Verify Disk too.
Preferences. Sometimes, older preferences do not play well with upgraded application compatibility for a new OS release. It might be worthwhile to delete the specific preference and its lock file from Lion.
Caches. As routine, just before I shutdown the system, I will move the contents of /Users/name/Library/Caches to the Trash. I tolerate Adobe Flash and use their preferences panel to delete all Flash content. Then on reboot, I delete the Trash. Application performance improves as a result.
File Directory. Everytime that I upgrade OS X and run the retail Disk Warrior 4.4, it reports 25% storage fragmentation. Repairing and rebuilding the File Directory always restores noticeable I/O performance.
Storage. If within your budget, upgrade to an SSD. Otherworld Computing has MBP SSD solutions.
Applications. Some non-Apple applications may need recompilation for Mountain Lion, or behavior may be questionable. I compile my own MacVim editor from github sources. The same 64-bit binary that was compiled with XCode 4.3 on Lion, misbehaved on Mountain Lion. Rebuilt it with XCode 4.4 and worked fine.
