Safari problems on iMac G3 slot-loading CRT

I'm posting here because I haven't been able to get a satisfactory solution to the problem on the Safari discussion board. Here goes.
I recently upgraded my son's iMac DV (A G3 processor) to OS X 10.3.9. Was having trouble launching Safari 1.3. It would start to launch and then quit. Here's the chain of events of fixes I've tried:
1) Machine -- iMac DV (G3) w/ slot loading drive -- was running OS 9.2.2 I tried to upgrade it to 10.3 with Panther discs. It told me I needed a firmware update, which I installed, then upgraded from the disc. Firmnware is now listed at 4.1.9f1 (Anybody know if this is as it should be?)
2) I then upgraded further with a 10.3.9 Combo download, which installed Safari 1.3. However, when I double-click the Safari icon, it won't open. Nor will it allow me to upgrade to 1.3.1 or 1.3.2.
3) I then downloaded Safari 1.2 again and re-installed that. That seemed to work and at least allowed me to get on the Web. But now, I'm back at version 1.2.
4) I tried repairing permissions. No go.
5) In desparation, I performed an Erase and Install of the system software from the Panther discs and got it back to 10.3.9 via the combo download. It then allowed me to update Safari to 1.3.1 and then 1.3.2, but it still won't launch.
I did the same thing to my daughter's iMac G3 and it all went fine. Only difference was, I was upgrading her from OS 10.2.8 and when I did, it did not ask me for a firmware update.
Any suggestions anyone?

Jamie,
Not being sure of what was suggested in the Safari forums....a few questions.....
* When you were able to get Safari to 1.3.1 did this open ok and just not 1.3.2?
* Not sure if it will help much but did you try trashing the Safari .plist file after downloading 1.3.2 (found @ ~/Library/Preferences/com.apple.Safari.plist) to see if that would help?
* Have you checked out Dr. Smoke's X-Lab FAQ for Multiple applications quit unexpectedly or fail to launch?
Personally, I doubt the firmware update (and yes that is the correct version you are showing) is to blame for the Safari failure but someone else may see it differently.

    That's what we needed.
    Officially your iMac--known as a "tray-loader" for its optical drive type--can go to Panther (10.3.X). Panther is quite better than Jaguar (10.2.8) that you now have. You probably need more RAM than 160MB for even Jaguar. I feel that 384MB is about min for that OS.
    The big problem is that the early iMacs came with painfully small hard drives --4 to 6 G--and OSX need a lot of free space on the disk for efficient performance. It's hard to keep a Jaguar system under 2G with a few useful apps installed.
    Bottom line: you'll spent money for a hard-to-find retail OS install disk, more RAM, and a bigger hard drive, and you'll still have a slow computer that will always struggle with modern web pages. If you want to upgrade and experiment as a hobby or learnign experience and you can afford the parts and time, by all means--go for it. However, if cost is an issue, throwing money at this unit is not cost-effective in terms of how much more yo ucan get from it.

  • IMac 350 slot loader: Display VERY VERY DARK-?

    IMac 350 slot loader: Display VERY VERY DARK. I have a slot loader 350 imac. The display is so dark its unusable until night time when I came make out most of the desktop. I have OS X installed, 9.2.2 installed and upgraded the firmware. I also replaced the RAM and tried booting from a CD. Nothing helps. The iMac works but is very dark. The Monitor control panel is set at max contrast and brightness set to max now, too. No relief. Any ideas? It must be hardware at this point.

    I'm wrong. It's the sign of a dying CRT. You can have a look at this possible repair.

  • Can't install OS 8.6 on iMac DV Slot Loading - firmware?

    I have an iMac "DV" (400) Slot Loading (http://support.apple.com/specs/imac/iMacSlotLoading.html) that I am trying to install the original system on (8.6, if I'm not mistaken). It has 128 mbs of RAM, a 10 gb HD, and currently no system installed on the hard drive. I have updated the firmware to 4.1.9.
    The problem is that the iMac won't boot from the install CD for me to do the installation. The iMac used to have OS 9 installed on it, and when I tried to run the installer with the computer booted from 9, it told me it couldn't run on this machine. I believe I have the correct installation CD. I have also tried a couple of other installation CDs, and neither 8.5 or 8.6 will boot this computer.
    Is there a way I can get 8.6 installed on this machine with the 8.6 CD, or is it just not possible for me to install 8.6 any more?
    Could the firmware update be preventing me from booting from 8.6?
    Thanks,
    Jon
    iMac "DV" (400) Slot Loading   Mac OS 8.6 or Earlier  

    http://docs.info.apple.com/article.html?artnum=25517 shows that later releases of the same iMac came with 9.0 through 9.0.4. Those that did can't use an 8.6 install disk.
    You can sometimes plug in the serial number of the Mac in the http://www.apple.com/support/ search engine at the bottom right hand corner of the page where it says to do so, to get an idea of how old the Mac is.
    Knowing that date, will tell you the likely operating system to have been installed. Since 9.0 was released in October 1999, a date after October 1999, would indicate the Mac can't boot 8.6.

  • Problems installing OS 9.2.2 onto a clean iMac G3 (slot loading)

    The iMac in question is completely clean yet for some reason will not boot from my retail Apple OS 9 disc. It boots just fine from my OS 10.1.5 disc, but will not start the OS installer when I use the OS 9 one.
    I need to update the computer's firmware so I can upgrade to more recent versions of OS X, but if I cannot get OS 9 on there first, I don't know what I can do.
    When the machine boots up I insert the OS 9 disc and hold down C. It will eject the disc, but if I push the disc back in once it fully ejects, it'll start searching for a start up disk before finding the disc. Then the screen will go gray and the CD will eject again. This time, still holding down C, I reinsert the disc and a floppy disc icon with a question mark flashes on the screen.
    What can I do?

    Actually, even the last iMac G3 only came with 9.1, so that disk may be for an early iMac G4.
    Is the iMac able to boot other optical disks (like the one for Mac OS X installation)? If so, the drive is OK, so it is probably the disk being for a significantly different and later Mac model. The 9.2.2 disks in particular seem to be very model-specific.
    Ideally, you should get a retail disk that is 9.0.4 or later. It should be white with a big orange 9 on it, and it should NOT say "upgrade" on it. The only retail disk your iMac may not be able to use is the original 9.0 disk (sold when Mac OS 9 was first released). You can get it up to 9.2.2 from any version of Mac OS 9 with free downloadable updaters

  • Safari Problems (Slow, Pages won't load, etc)

    Hi,
    My MBPro is less than a year old. All software is up to date.
    My new 802.11 AC router is installed without a problem.
    Safari keeps lagging in loading pages. Sometimes they just don't load.
    I thought it was the router or internet connection but it's not.
    Google Chrome is lightening fast.
    I've cleared cache, browser history, etc.
    Not sure what else to do.
    Any ideas?
    Thanks

    What version of the OS are you using?
    Safari/Preferences/Advanced - enable the Develop menu, then go there and Empty Caches. Quit/reopen Safari and test. Then try Safari/History/Show History and delete all history items.  Quit/reopen Safari and test. You can also try try Safari/Clear History and Web Site Data. The down side is it clears all cookies.Doing this may cause some sites to no longer recognize your computer as one that has visited the web site.

  • IMac DV slot-loading power button glows orange after shutdown, cant start

    Hi,
    I have iMac DV SE (graphite model) of 1999, 320MB RAM, 40 GB HD, running Mac OS X 10.4.7.
    Everything seems to work fine, but when I go to Shutdown, it shuts down fine and power light goes off...Then several minutes later, the power button turns orange and stays like that for a few hours and then goes off again.... Then several hours later or the next day, I have a hard time getting it to turn on again by hitting the power button.. the keyboard (old iMac keyboard) power button never works to turn on the iMac (should it?) but when I hit it while in Mac OS X, it shows me the menu to shutdown, restart, sleep, etc...
    Also, by PRAM battery seems good (I measured it at 3.6 V) and it seems to keep track of the date and time just fine, so I cant imagine it's the battery....
    So in the past when this happens, it just keep hitting the power button and/or remove the power cord and re-insert, etc, and some combination of that after many tries the iMac finally starts up...
    Any idea what's going on? I cant find any discussion of the power button going orange after a shutdown and the fact that my keyboard power button doesnt work to turn on the Mac...
    Help...
    Andrew

    Ah.. very interesting... I'm surprised I couldnt find any info on the 'net about this orange power light...
    Anyways, I found have some interesting stuff since...
    1. On this last occasion when it didnt turn on, I was jiggling some stuff (plugging and unplugging the power cord several times.... then I tilted the iMac slightly and let it "drop" to jostle/jiggle it)... and after the slight "drop," I hit the power button and it turned on just fine... d'oh... I wonder if something's just "loose" somehow... I dont have a random shutdown problem, once it's turned on and inside Mac OS X, it works fine for hours and hours until I tell it to shutdown. hehehe...
    2. Just last night, before going to bed, I shut it down and since it's plugged into a power surge, I turned the power OFF to the power surge, so now it doesnt have any power to it... so this morning, I turned power to the power surge, and hit the power button on the Mac and it turned on just fine! d'oh again.. hehe... so it almost leads me to believe somehow that leaving the power cord with electricity flowing to the Mac when the Mac is shutdown is "hurting" it somehow, and if there is no power connected when it's shutdown, it works normally (I think)...
    Very strange indeed...
    Anyways, I got this Mac second hand so I am wondering if this was a problem for the original owner... when I first got it , I knew the hard drive was missing, so I put a 40GB IDE hard drive from a PC and formatted it, etc... so not sure if the hard drive could cause a boot issue...
    Oh, well, I guess I'll keep using this iMac until it no longer turns on.. lets see how long I can keep going like this ..heheh..

  • Slot-loading DV Display/HardDrive seize up

    I am posting a conversation I have been having with a discussion board user, as I think it will be useful for others

    Hi Richard:
    I've just been reading an exchange you had with someone named Graham in the UK about his iMac going black and becoming unresponsive. After a series of exchanges, you finished up (I think) with:
    That can be a possibility. If it was the CPU temp that's causing this the entire logic board would have to have come loose or perhaps the conductive paste has dried out/failed, unlikely.
    So upshot. In my experience the part that fails in these G3 iMacs is the PAV (The board you see when you look down from the top it's under the CRT and drives the monitor section. The logic board derives power from the PAV via down converter).
    The shutting down is a classic symptom and the most irritating.
    Others: No start - power light blinks or turns amber, video gets wonky - color shifts or size variations, sparks arcing sound, native screen is dark but external monitor works fine (not on option on your 350, no external spigot). This is why I've got 7 or so iMac G3s in my basement. Mostly 350s since I was given around 20 of them and I repaired and donated most into the inner city. The ones left have PAV problems.
    Wacky upgrade options:
    I'm especially interested because here you mentioned the other main symptom I've noticed in my own version of the same problem: the "arcing sound" which I've been hearing almost from the start of my issues. Everything else almost mirrors his, except the time for the symptoms to kick in has reduced to less than 10 minutes.
    I thought it might be the drive, so I've tried 2 different hd's, and it happens with both, and I tried running the iMac (400jhz slot loading) just off of CD, and it shut down then too!
    Obviously, I've been inside the machine to replace the drives, with my teenage daughter's help (my eyes aren't so hot). I'm going to check for this OS X temperature software and see what it tells me. I did run a RAM checker, and it said it was all fine, so at least I know it's not that. I tried to get a version of Apple Hardware Checker for it (or whatever it's called) but it said the iMac DV would not run the software.
    Do you still have those . . . PVA's? This machine is a perfect print server and backup hd and work stereo, and we have enjoyed tinkering with her in the past. If it wasn't TOO complex, I'd like to give it a try. I showed my daughter how to solder a battery cable onto a tester circuit board, so if that's the kind of thing we'd need to do, I'm game.
    Let me know, and I'm looking for a temperature checker right now. Oh yea, and Tricia Helfer DOES look pretty hot.

    Hi Cary,
    the other main symptom I've noticed in my own version of the same problem: the "arcing sound" which I've been hearing almost from the start of my issues.
    That arcing sound is almost always the flyback transformer. That is on the PAV board which is basically the entire upper half of the computer. Here's a site in England where you can download the Service Manual for your machine.
    http://www.macmanuals.co.uk/
    So since you have a 400 MHz machine it's one of the more desirable machines since it has firewire. 400 to 700 had them. As I mentioned in my post I would pull the logic board and transfer it to a working 350. If you look in the manual swapping the board is simple. Then again around Chicago these G3 iMacs are sold for $25 or less. Don't know the situation where you are.
    I used to repair these but they've become so cheap that the board swap is now my chosen path.

    I guess this shhould've been on the discussion board so others could see it, but I'll just ask one more thing before looking into the manual:
    Remember, I've swapped a harddrive and memory, but board changing is something I've never tried before:
    So, are you saying that the PAv that might be creating these issues, being such a large part of the computer, should just be abandoned, and the logic board swapped into a 350 because of it's simplicity? Does the logic board contain the 400 mhz processor and firewire hookup, or would those be left behind on the 400 iMac's PAV board?
    I'm looking at the manual, and you're right, pulling the logic board does look pretty simple, but I haven't found the answer to the above question yet, so I'll send it to you.
    I emailed this to you because the original post a over a year old, and I wasn't sure you'd still be watching the discussion boards. Next time, I'll just 'trust to the boards', though I've only received 2/5 answers through it over the years.
    Thanks again.

    Carey,
    So look at the pic I enclose. It's from the service manual.
    So you've had the machine apart to this point, from here it's just the removal of the 10 screws to remove the logic board and down converter. They plug into the upper part via a couple of connectors. There could be a few plastic rivets that tie the board to the divider panel.
    Does the logic board contain the 400 mhz processor and firewire hookup, or would those be left behind on the 400 iMac's PAV board?
    That's all on the logic board.
    Basically the iMac is a CRT display and speakers with a logic board underneath with the optical drive and the hard drive.
    The board on top is called the PAV board ( power analog video) i. e. video power supply for a computer monitor. Power comes from that board and comes down to the "down converter" which changes it to logic board power, basically 12V and 5.5V DC. (These boards have been run "headless" but now not worth the trouble)
    So your path from here will be determined by what kind of donor iMac you find. It must be a slot loader and the chances are it will be as fast or faster as your current machine.

    Hi Richard:
    Well, despite your own circumstances with blueberries and strawberries falling from the computer sky, I've gone on 4 different user forums and several different 'used things for sale' websites, and so far the closest I can come to getting a used imac is having one shipped from the next province (about 500 miles) for about 50-60 bucks, or possibly one in the city which the poster said they wanted 200 bucks for. I've had no reply to my email to them, yet.
    Would you be willing to sell me one of those PAV boards, if they're still kicking around? I would think the shipping would be much less than the whole darned computer.
    If you don't still have them in piles around you, I may just have to turf the iMac entirely for budgetary reasons.
    I guess with the much smaller population, the proliferation of iMacs is similarly reduced. There's only about 3 million people in Alberta, which is where I am.
    Let me know.
    Greatly appreciate the information connections you've made for me.

    Hey Carey,
    Well I was forced to leave all of my iMac G3 parts with a recycler in Chicago when I moved.
    I actually found one here in Pocatello (town of 60K) for $25 so maybe you can find the same thing. I don't have a PAV board and they are very hard to swap out, don't think I ever did it.
    So, thinking a bit more about your situation, since you're using it as a server, when it fails does it absolutely freeze up? On the 400 you can attach a VGA monitor to the spigot under the perferated oval grill under the bottom rear. The monitors can fail in these and still produce power to run the logic board. Around here you can get a cheap LCD 15" monitor for around $25. A CRT type you can probably get for free. So if you're lucky it can still work that way.
    There were people who ran a logic board headless, but most of these are out of date:
    Here's a few:

    Soo hopefully yours will fail and just the CRT will be involved.

    <Edited by Host>

    Perhaps one of your RAM modules has gone belly up. To test this, remove both RAM modules and start up. If the RAM is the cause of the problem, the computer will respond with a complaining chime, and of course go no further. But that will indicate the RAM is cause, and you can go to the next step; try to start up with just one of the RAM modules installed - either one. If that gets you nowhere, try the other one.
    If the problem is not bad RAM, it is beyond my expertise to help. Sorry.

  • IMac CRT slot loader doesn't get past apple symbol at startup

    I've got an old iMac CRT, 600mhz slot loader that I want to give away to a friend.
    I've lent it to a couple of people in it's life (I now have a different computer), and I can't find the system disks.
    The computer had Panther installed on it (can't find those disks either - can't remember how I even got Panther on to it) and was working fine. I deleted all the old users off it to just have my friend's user ID. So technically, there was nothing personal on the computer, just a bunch of applications. However, out of the 40 gigs of HD space, it was telling me that there was only 9 available, which I found strange.
    Anyway, while I was installing Adobe CS on it, just before it was finished I tried to find out where all the HD space was being used. So I opened the Applications folder and did Apple-I to get info. When the dialogue window opened, it said it was calculating folder size.
    As this was happening while I was also installing CS, I didn't worry about it, just thought it would complete after installation was finished. However, this didn't happen, and I found that not only did the folder size not get calculated, the whole computer had frozen. Not even a force quit would do anything, it was like an old fashioned system 9 crash.
    So I forced shut down and tried to start up again. So now it won't get past the OS X grey apple screen. Not even the spinning dial appears and you just see the apple icon for eternity. Have tried zapping PRAM, holding down option key, shift key. Nothing works.
    So I'm wondering: what do I need to do to get it to work? Do I need the system disks? Or is there some other way to fix this?
    Thanks in advance,
    Lachlan

    http://docs.info.apple.com/article.html?artnum=106464
    My guess is that you are going to need System disks available here.
    Good luck. These things get really frustrating.

  • IMac Slot Loader Problems Upgrading from os 9 to Tiger

    I have an iMac Slot loader that i want to bring up to tiger. The firmware is at 4.1.9, it runs panther fine, but when i install Tiger via Firewire it freezes on the reboot.

    ok. I did everything that the reference document told me to do. The onl thing i get now is a Gray screen with the startup music that u get when you get ready to setup tiger. The firmware is up to date i know that i checked it before starting the install. I have gotten rid of all third party ram and still that is all i get i am so lost and confused on this one. I am about ready to give it the parking lot slide. Anyway thanks for the help but we are closer but close doesnt count except for in horse shoes, hand grenades, and atom bombs.

  • Can't install OS 8.6 on iMac "DV" (400) Slot Loading?

    I have an iMac "DV" (400) Slot Loading that I am trying to install the original system on (8.6, if I'm not mistaken). It has 128 mbs of RAM, a 10 gb HD, and currently no system installed on the hard drive. I have updated the firmware to 4.1.9.
    The problem is that the iMac won't boot from the install CD for me to do the installation. The iMac used to have OS 9 installed on it, and when I tried to run the installer with the computer booted from 9, it told me it couldn't run on this machine. I believe I have the correct installation CD. I have also tried a couple of other installation CDs, and neither 8.5 or 8.6 will boot this computer.
    Is there a way I can get 8.6 installed on this machine with the 8.6 CD, or is it just not possible for me to install 8.6 any more?

    Hi Jon
    Load the install CD into the Mac then power off (with the CD still inserted), on rebooting but before the chime, hold down letter C on the keyboard, that will boot from the install CD to let you do a system install.
    You did not note whether you had other programs/files on the iMac that you want to keep, but if not, I would suggest that you do a complete "clean install" by re-formating/initializing the HD, then install the OS.
    I would also suggest that you partition the HD into 3 (or more) partitions, 1 for the main system, 1 (or more) for your other programs/files and 1 for a "back up system", the logic being the main system is your default "boot-up" while the "back-up" system is what you boot to do maintenance/de-frag etc on the main system with a utility such as Norton's Utilities or similar.
    I would also suggest that you have a copy of Norton's (or similar) on both systems, that way you can "chop and change" systems to do the maintenance. Proper maintenance/de-fraging cannot be done to the "boot-up" system that you boot from.
    Hope this is of some help.

  • Optical Drive/slot loading drive not recognized by imac G5. HELP US!!!!!

    We have an imac G5 that is maybe 14 months old. I know for a fact that the slot loading optical drive on the side has been used for three things in the entire time we've owned it. That's THREE TIMES in 14 months and now it's as if the drive doesn't exist on the computer. I've gone into the system profiler, it says there is no drive, try to put in a cd, no resistance, no noise and it doesn't even try to suck in any disc. Has anyone else experienced this? Have you figured out what to do? I can replace the drive myself, it's not hard but can someone recommend a good quality drive cause I'm not paying through the nose for parts from apple only to have them crap out on me.
    I feel ripped off!

    We have 3 right now having problems. 1 just went into the ITech store to have a CD removed. 1 will not even accept a CD anymore and the other just makes awful noises and scratches the CD. These have been minimally used also. They said the Optical Drive is bad on the 1st one. Of course, we are 1 month past our warranty! I think Apple should be backing this but when I called about it they didn't want to help me. Even saying I had not registered them even though I had documentation from them saying I had. I know the feeling of being ripped off. Our company has purchased 20 of these in the last 1 1/2 years. You think we would get a little bit of help from Apple being we have purchased so many of their products in the last 20 years.

I think Apple should be backing this but when I called about it they didn't want to help me. Even saying I had not registered them even though I had documentation from them saying I had. I know the feeling of being ripped off. Our company has purchased 20 of these in the last 1 1/2 years. You think we would get a little bit of help from Apple being we have purchased so many of their products in the last 20 years.

  • Clients running OS 10.4.6 on older iMac (slot loading) cannot login

    Clients running OS 10.4.6 on older iMac (slot loading) cannot login. I get:
    “Logging into the account failed because an error occurred. The home folder for the user account is located on an AFP or SMB server. Contact your system administrator for help."
    I have eMacs and iBooks on this network running 10.4.6 and they have no problem. Also the iMacs running 10.3.9 have no problem. Since it’s machine and OS specific I’m wondering if it’s an incompatibility problem. The iMacs have the latest firmware on them. The server is a G5 running 10.4.6 server, DNS and DHCP are setup correctly and the share points are setup correctly.

    Try resetting the PMU/SMU and PRAM/NVRAM. You'd need to identify the mode of resetting depending on the model of your G5 iMac. The Apple support sites that would help you for this are –
