Extremely slow mac mini

i am using a mac mini with 2 GB of ram and 2.3 intel core i5, my os is OS X 10.7.5, recently, my computer has been extremely slow, for every click i did, it takes at least 10 seconds to respond, i could not find out why.

Back up all data immediately as your boot drive may be failing.
This diagnostic procedure will query the log for messages that may indicate a system issue. It changes nothing, and therefore will not, in itself, solve your problem.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'GPU D|I/O|find tok|n Cause: -|timed? ?o' | tail | open -ef
Copy the selected text to the Clipboard by pressing the key combination command-C.
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.

  • Backing up catalog from inside of lightroom extremely slow (30 min)

    I have a catalog that is just under 5gb, if I navigate to the folder where it is stored and copy paste it onto my backup drive it copies in under 2 min. However, if I chose to backup my catalog on exit from inside lightroom it takes over 30 minutes (not counting testing etc). Obviously I can backup my catalog manually, but it would be nice if the built in backup feature worked like it's supposed to.
    I'm running win 7 64
    lightroom 64 same probelm in 4.3 and 4.4
    the catalog and lightroom are stored on a ssd drive
    backing up to a NAS ( my typical transfer speeds are 60-80 MB/s)
    Thanks for any thoughts
    -Dan

    I tried to the local ssd with only a small improvement. Like I said, if I navigate to the catalog manually and copy and paste it to the NAS it takes under 2 minutes... (80+ MB/s), but done through lightroom it just crawls.  Lightroom either has a bug, or it's doing something much more than just copying the catalog to the selected directory. I've tried it with and with out check and optimize.

    A 5 GB Lr catalog is a hefty catalog. But 30 min seems a bit long even for that. I suspect that the NAS drive or its connection speed are slowing things down.Try this: Create a catalog backup from within Lr to an internal drive to check whether that will speed up the process.

  • Unbelievably slow mac mini

    Hi all,
    I have a 4 day old mac mini which has been running extremely slowly since purchase (much slower than my old powermac g5)
    I'm getting pinwheels just using safari, delays in typing, programs opening very slowly and is just generally sluggish... it does however start up and shut down quickly. I have been in contact with apple and gone through resets and archive installs etc but still no improvement.
    Are they supposed to run this slowly? I didn't play around with one in store but can only assume they should be running faster.

    If it appears to be practically everything and you've already went through all the steps over the phone/online then really you've used up enough of your time and it would be best to take it in. Even if you did find a way to fix it you've gone through enough hassle that at the minimum the genius bar should take a look at it. Otherwise back to the purchase place.

  • Very Slow Mac Mini / Decreasing Memory?

    Hi,
    Unfortunatly I'm having a problem with my Mac Mini. For an unknown reason my Mac Mini (Mac OS X 10.6, Snow Leopard) has been running extemely slow the last few days. I have reset the Mac a countless number of times now and done everything I can think of to fix the problem. I have noticed that occasionally the Mac will work fine for a few minutes, until suddenly the free space on my Macintosh HD will start to decrease. Roughly 1 or 2 GB of free space starts to disappear every few minutes. Please could someone offer me some help. I would be extremely greatful.
    Thanks a lot,
    Ant

    Thanks for the welcome.
    The only thing I am running is Finder. For the first 3-4 minutes though everything is fine, no matter what I run (e.g. Internet...). The problem only occurs when the Macintosh HD available free space starts to randomly decrease every few minutes.

  • My Slow Mac Mini - will someone once and for all give me an answer!!

    I got a 1.25 ghz Mac Mini with 512 RAM running 10.4.4 . This thing has been so slow since I pulled it out of the box. I always get the colorwheel when doing just about anything. No, I don't have a bunch of apps open, just Safari and Mail. I tried closing Dashboard, but that did not help. There is also this lag, when I mouse over my dock, it does not immediatly respond. This is no fun. Does someone have an educated answer for this problem?

    Robert,
    If you restart your mini, does it act this slow from the start? Or is it when you use it for a period of time?
    Also, open Finder, and click on the Applications section. Look for a program called Activity Monitor (it may be in a folder called Utilities). When that opens, there is a section called Memory (may be Memory Usage). Click on this and sort by Memory on the list. This will show programs that are using significant amounts of memory. My hunch is that a program is eating up all available memory and slowing your mini down. The most likely culprit is Safari. To quit Safari, you have to actual select from the menu, the Quit option. Just clicking on the X will not close Safari.
    Post back with the answers to my first two questions. Also, post back with what you find in the Activity Monitor program. There are lots of people here that are more knowledgeable than me, so hang in there, we'll find the answer.

  • Slow mac mini

    Mac Mini G4, 1.33 GHz 512 MB OS 10.4.11
    Has suddenly begun slowing down when I have been loading web
    pages. This occurred a day or two after I installed Apple's Sept. 15
    Security Upgrade.
    Also, I found a drop-down message in my network
    preferences that said "Your network settings have
    been changed by another application." This drop-down would not go
    away, preventing me from accessing any of my system preferences, a
    problem noted by many others in the discussions here. Based on
    advice found in the discussions here, I managed to delete the drop-down message after much hair-pulling, but I am now left with a computer that has slowed
    by about 20 percent.
    I have had a tech do cleaning,repairing, and troubleshooting with no appreciable improvement inweb-loading speeds. Do you have an answer for me? Are there others experiencing this slowdown after the Sept. 15 Security Upgrade?
    Would uninstalling my Sept. 15 upgrade bring my system back to is
    earlier speeds? Help!

    Hi, Andy-
    I will do my best to answer your questions. Thanks for you help.
    Thanks for getting back to me.
    The primary web page loading issue is: when I attempt to launch a page, it consistently pauses from 10-20 seconds or longer before a 3/4 partial page snaps up on the screen, then takes more time (often 15 seconds or more) to fully load. This did not occur before the Sept. 15 security update; I could navigate smoothly from web page to web page.
    A tech cleaned my caches, reset Safari, ran MacHelp mate, checked preferences and permissions for corruption via Utility, ran auto-maintenance scripts and went to Activity Monitor to see if any
    applications were putting an unusual CPU or memory load on the system during startups (none appeared to be, Safari's maximum load around 40-60 CPUs as it initially struggled to load a page).
    The Mac Mini is less than three years old, and I don't run games or other memory-draining applications.
    I hope this helps you help me.

  • Slow Mac Mini with i7 quad core (current gen.) with most current OSX vs. a PC-Winodws 8.1

    My Mac Mini is somewhat slow... don’t get me wrong it’s a fast computer but I got a new work laptop i5 Dual Core Acer laptop with windows 8.1 (I know LOL)
    & it is so much faster with media and browsing the web and overall boot up everything.... Now I have started to leave my Mac on all the time (sleep vs. off) and its much better but having multi-webpage’s up and YouTube it still get slow and will ever crash from time to time...
    Anyone else has this issue? Know what can be done?
    Maybe it’s just because the i5 on the Acer is a newer Haswell design? But the Mac is quad core…. Even my old PC desktop that I never use with an Intel Core 2 quad is so much faster even at 8 years old; boots Windows in 9 sec.
    Mybe is just OSX - I'm thinking about install WIndows 8.1 on the Mac Mini.... ( anyone have this option; is it fast?)
    Thanks

    Sometimes all Apps stop working or take a long time to come back.. Have to restart.
    These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
    Step 1
    For this step, the title of the Console window should be All Messages. If it isn't, select
    SYSTEM LOG QUERIES ▹ All Messages
    from the log list on the left. If you don't see that list, select
    View ▹ Show Log List
    from the menu bar at the top of the screen.
    In the top right corner of the Console window, there's a search box labeled Filter. Initially the words "String Matching" are shown in that box. Enter "BOOT_TIME" (without the quotes.)
    Each message in the log begins with the date and time when it was entered. Note the timestamps of the BOOT_TIME log messages, which refer to the times when the system was started. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Select the messages logged before the boot, during the time something abnormal was happening. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
    For example, if the system was unresponsive or was failing to shut down for three minutes before you forced a restart, post the messages timestamped within three minutes before the boot time, not after. Please include the BOOT_TIME message at the end of the log extract—not at the beginning.
    If there are long runs of repeated messages, please post only one example of each. Don’t post many repetitions of the same message.
    When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    ☞ Some private information, such as your name, may appear in the log. Anonymize before posting.
    Step 2
    In the Console window, select
    DIAGNOSTIC AND USAGE INFORMATION ▹ System Diagnostic Reports
    (not Diagnostic and Usage Messages) from the log list on the left. If you don't see that list, select
    View ▹ Show Log List
    from the menu bar.
    There is a disclosure triangle to the left of the list item. If the triangle is pointing to the right, click it so that it points down. You'll see a list of reports. A crash report has a name that begins with the name of the crashed process and ends in ".crash". A panic report has a name that begins with "Kernel" and ends in ".panic". Select the most recent of each. The contents of the report will appear on the right. Use copy and paste to post the entire contents—the text, not a screenshot.
    I know the report is long, maybe several hundred lines. Please post all of it anyway.
    ☞ If you don't see any reports listed, but you know there was a crash or panic, you may have chosen Diagnostic and Usage Messages from the log list. Choose DIAGNOSTIC AND USAGE INFORMATION instead.
    In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.)
    ☞ Please don’t post other kinds of diagnostic report—they're very long and rarely helpful.

  • Help me diagnose my slow Mac mini

    Hi All,
    I bought my wife a Mac mini (2012) and all she does on it is email, web and chat (Google Hangouts, typically). She did all of this on her old 2007 iMac, but for some reason this new Mac mini is struggling hard. She will get the spinning beach ball of death very very frequently when just switching between tabs and between her browsers. She will typically have Safari and Firefox open at the same time doing different tasks in each one, but they're usually just displaying websites.
    Its her computer, she uses it all day long but it will typically only exhibit the slow behaviour when I am at work. She's not very technical and wouldn't know what to look for to see if there is a runaway process or something of that sort. Ideally, what I would like is to have some kind of program running to capture CPU, memory and disk usage and let me see which process is doing what at certain times a day. Specifically, when her CPU gets pegged and things start to freeze up I want to see some kind of log or graph showing what each process was doing at the time, how much cpu they were using, and memory/disk usage. I know Activity Monitor shows this stuff real time, but is there a way to capture that to a log so I can examine it when I am there?
    She is at her wits end and its frustrating for me because she can't replicate it when I am home.
    Any help would be appreciated.
    Trevor
    PS: Mountain Lion, all updates. 4GB RAM, lots of disk space left.

    First, back up all data immediately, as your boot drive might be failing.
    There are a few other possible causes of generalized slow performance that you can rule out easily.
    Reset the System Management Controller.
    If you have many image or video files on the Desktop with preview icons, move them to another folder.
    If applicable, uncheck all boxes in the iCloud preference pane.
    Disconnect all non-essential wired peripherals and remove aftermarket expansion cards, if any.
    Check your keychains in Keychain Access for excessively duplicated items.
    Boot into Recovery mode, launch Disk Utility, and run Repair Disk.
    If you're booting from an aftermarket SSD, see whether there's a firmware update for it.
    Otherwise, take the steps below when you notice the problem.
    Step 1
    Launch the Activity Monitor application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Activity Monitor in the icon grid.
    Select the CPU tab of the Activity Monitor window.
    Select All Processes from the menu in the toolbar, if not already selected.
    Click the heading of the % CPU column in the process table to sort the entries by CPU usage. You may have to click it twice to get the highest value at the top. What is it, and what is the process? Also post the values for % User, % System, and % Idle at the bottom of the window.
    Select the System Memory tab. What values are shown in the bottom part of the window for Page outs and Swap used?
    Next, select the Disk Activity tab. Post the approximate values shown for Reads in/sec and Writes out/sec (not Reads in and Writes out.)
    Step 2
    If you have more than one user account, you must be logged in as an administrator to carry out this step.
    Launch the Console application in the same way you launched Activity Monitor. Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
    View ▹ Show Log List
    from the menu bar.
    Select the 50 or so most recent entries in the log. Copy them to the Clipboard (command-C). Paste into a reply to this message (command-V). You're looking for entries at the end of the log, not at the beginning.
    When posting a log extract, be selective. Don't post more than is requested.
    Please do not indiscriminately dump thousands of lines from the log into this discussion.
    Important: Some personal information, such as your name, may appear in the log. Anonymize before posting. That should be easy to do if your extract is not too long.

  • HT4432 slow mac mini

    slow mini mac

    You'll need to provide some more information for anyone to help you. Start with which mac mini do you have? Click the apple on the left of the menu bar, and about this mac ... what processor, memory, and operating system do you have? What size disk drive do you have and how much free space do you have? Did you buy the system with the current operating system or did you upgrade? If upgraded, when?

  • 10.9.2 Update Slowed Mac Mini

    Hello,
    Since updating I have been almost unable to use my Mac due to it running extremely slow. Startup and opening applications feels like I'm on a Windows 95. I would like to restore to the last OS but don't have anything backed up. Any Suggestions?

    1. This procedure is a diagnostic test. It changes nothing, for better or worse, and therefore will not, in itself, solve the problem.
    2. If you don't already have a current backup, back up all data before doing anything else. The backup is necessary on general principle, not because of anything in the test procedure. There are ways to back up a computer that isn't fully functional. Ask if you need guidance.
    3. Below are instructions to run a UNIX shell script, a type of program. All it does is to collect information about the state of the computer. That information goes nowhere unless you choose to share it. However, you should be cautious about running any kind of program (not just a shell script) at the request of a stranger on a public message board. If you have doubts, search this site for other discussions in which this procedure has been followed without any report of ill effects. If you can't satisfy yourself that the instructions are safe, don't follow them. Ask for other options.
    Here's a summary of what you need to do, if you choose to proceed: Copy a line of text from this web page into the window of another application. Wait for the script to run. It usually takes a few minutes. Then paste the results, which will have been copied automatically, back into a reply on this page. The sequence is: copy, paste, wait, paste again. Details follow.
    4. You may have started the computer in "safe" mode. Preferably, these steps should be taken in “normal” mode. If the system is now in safe mode and works well enough in normal mode to run the test, restart as usual. If you can only test in safe mode, do that.
    5. If you have more than one user, and the one affected by the problem is not an administrator, then please run the test twice: once while logged in as the affected user, and once as an administrator. The results may be different. The user that is created automatically on a new computer when you start it for the first time is an administrator. If you can't log in as an administrator, test as the affected user. Most personal Macs have only one user, and in that case this section doesn’t apply. Don't log in as root.
    6. The script is a single long line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, though you may not see all of it in the browser window, and you can then copy it.

    Copy the selected text to the Clipboard by pressing the key combination command-C.
    7. Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
    Click anywhere in the Terminal window and paste (command-V). The text you pasted should vanish immediately. If it doesn't, press the return key.
    8. If you see an error message in the Terminal window such as "syntax error," enter
    exec bash
    and press return. Then paste the script again.
    9. If you're logged in as an administrator, you'll be prompted for your login password. Nothing will be displayed when you type it. You will not see the usual dots in place of typed characters. Make sure caps lock is off. Type carefully and then press return. You may get a one-time warning to be careful. If you make three failed attempts to enter the password, the test will run anyway, but it will produce less information. In most cases, the difference is not important. If you don't know the password, or if you prefer not to enter it, press the key combination control-C or just press return three times at the password prompt. Again, the script will still run.
    If you're not logged in as an administrator, you won't be prompted for a password. The test will still run. It just won't do anything that requires administrator privileges.
    10. The test may take a few minutes to run, depending on how many files you have and the speed of the computer. A computer that's abnormally slow may take longer to run the test. While it's running, there will be nothing in the Terminal window and no indication of progress. Wait for the line
    [Process completed]
    to appear. If you don't see it within half an hour or so, the test probably won't complete in a reasonable time. In that case, close the Terminal window and report the results. No harm will be done.
    11. When the test is complete, quit Terminal. The results will have been copied to the Clipboard automatically. They are not shown in the Terminal window. Please don't copy anything from there. All you have to do is start a reply to this comment and then paste by pressing command-V again.
    If any private information, such as your name or email address, appears in the results, anonymize it before posting. Usually that won't be necessary.
    12. When you post the results, you might see the message, "You have included content in your post that is not permitted." It means that the forum software has misidentified something in the post as a violation of the rules. If that happens, please post the test results on Pastebin, then post a link here to the page you created.
    Note: This is a public forum, and others may give you advice based on the results of the test. They speak only for themselves, and I don't necessarily agree with them.

  • Airport Extreme and Mac Mini on different networks

    Hello ALL,
    I am creatng a Mac Mini server. I have the Mac Mini connected via ethernet to my new Airport Extreme. I read somewhere that for server purposes, I should wire the mac mini versus using the wireless connection.  My Extreme is bridged with the Uverse 2wire modem and I have wifi disabled on it.  The problem I have s my ipad and iphones are all on the wireless network created . I use remote apps for the mac mini. As of now the remote apps do not recognze the mac mini becuse its connected via ethernet.  Any solutions for ths? Can i turn on Ethernet and Wireless at the same time?    THANKS!!

    My Extreme is bridged with the Uverse 2wire modem and I have wifi disabled on it.
    The it on the end of the sentence could equally refer to the Extreme or the 2wire.
    I think you mean the Extreme.
    Can i turn on Ethernet and Wireless at the same time?
    The context suggests you are talking about the mac mini but you could equally well refer to the Extreme.
    Do not mix up domains.. I think this is what the problem is. If you have wireless on the 2wire and the idevices are getting IP from the 2wire, they are also getting a domain.
    Mavericks is very sensitive to domain. The domain by default on the AE is local .. but the domain on the 2wire could well be your ISP.
    I would recommend you turn wireless on .. on the Airport Extreme.. not on the Mini. And see if the idevices when connected to the same domain can then also connect to the mini.
    Tell me your results.
    A netstat scan is a great tool to use in the Mac.. open the network utility and see what you get for domains. See if the phone etc are on a wrong domain.

  • Extremely slow Mac after updating to Snow Leopard from Leopard

    Hi, I just updated to Snow Leopard from Leopard, and now everything is extremely slow, things keep crashing, freezing etc. What did I do wrong? How do I fix it?

    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.
    Download and install Mac OS X 10.6.8 Update Combo v1.1.

  • Airport Extreme + MBP + Mac Mini

    hi all. i am really not into networks that much. so forgive me if i sound like a 5 year old. (nowadays even 5 year olders are experts anyway). i have an airport extreme and a macbook pro and a mac mini wirelessly connected to it. Mac mini has external hdd attached to itself and uses as it's time capsule. I've attached another one to the airport extreme as a time capsule for the mbp. the thing is i cannot access the hdd attached to the airport extreme by any means. and the airport extreme itself does not recognize the drive either. if i attach it to the mbp it is recognized and the system asks if i want to use it as a time capsule. but when i attach it to the airport extreme, even in the airport utility>disks tab i dont see it. and in finder i do not see my airport extreme under the shared on the left column. but the mbp and the mac mini are visible to each other. i'd appreciate if anybody can give me a heads up on this.
    the os is 10.7.3

    I've attached another one to the airport extreme as a time capsule for the mbp. the thing is i cannot access the hdd attached to the airport extreme by any means. and the airport extreme itself does not recognize the drive either
    Apple does not officially support Time Machine backups to a drive at the USB port of the AirPort Extreme, so that might explain some of the difficulty here.
    Some users seem to be able to make this work, while some have only some success and some (like me) have no success despite repeated attempts.
    If you want to try this anyway, the drive must be formatted in Mac OS Extended (Journaled) and a powered USB hub is often required for the hard drive.....even if it has its own power supply.

  • Best strategy for using external drive to speed up painfully slow mac mini

    I have Intel core duo, and LaCie external drive. Many programmes are almost unusably slow. Like Adobe Photoshop, Garageband, Logic Express, SecondLife etc... (would have been nice if apple had told me the 'improved spec' would mean so many programmes would no longer work!)
    I am looking for the best way to utilise the external drive. I have now set up to boot from the LaCie, but it is no better. Id like to know whats best to do with the two drives. Would one be best kept as clear as possible? And should that be the bootup drive? Originally, the idea was to increase storage and backup. Now it is anything at all, that will make this computer faster. My old G4 PowerMac is actually faster and more reliable!
    powerMac G4   Mac OS X (10.3.9)  
    powerMac G4   Mac OS X (10.3.9)  
    powerMac G4   Mac OS X (10.4.9)  
    powerMac G4   Mac OS X (10.3.9)  
    powerMac G4   Mac OS X (10.3.9)  
    powerMac G4   Mac OS X (10.4.9)  

    There is no way to improve on the graphics card in your mini - it's built into the logic board and can't be bypassed. However, while that may be a disappointment, it has to be said that by and large the graphics system in the mini is actually very capable, and is probably not the cause of the problem.
    What IS the primary issue I suspect is the 512Mb RAM, which on a Core Solo running applications such as Photoshop is so woefully inadequate that it would be a surprise if your old G4 wasn't somewhat faster!
    The problem is that Photoshop (the version you have) is not Intel-native, so while it runs, it requires Rosetta. Thus you have a RAM-hungry operating system, a RAM hungry application and a RAM-hungry translation package, all running at the same time. To add to that, since the software is not Intel-native, it has to be translated on-the-fly so considerable CPU time is needed to devote to that process in addition to all the other things the system needs to do in order to run.
    Thus your external drive would not help much when used as a boot drive because even though it is likely to be somewhat faster than the internal, the limited RAM of the system will be forcing so many 'paging' actions (writing and reading memory blocks to the hard drive) that any speed gains will be rather heavily masked.
    Most of the performance problems you experience can be resolved by upgrading RAM to 2Gb, simply because that will allow MacOS, Rosetta and your software a lot more room to breathe and significantly reduce the paging activity of the system such that then booting from the external will show notable improvements in responsiveness.
    Alternatively, you may find that there are Intel-native alternatives to your software which may be available at reasonable cost and provide the features you need. Good examples are such things as GraphicConverter, which is shareware and does much of what Photoshop can do, and NeoOffice, which is open source and free, which is a good alternative to MS Office. These would run without Rosetta and provide you with much improved performance as a consequence.
