Re: IMac problem.

[Alan Smith]

Hi Tony,

Another opinion.  My 27” 5K  iMac is in a room with airconditioning turned off. 
 I am not “working” the mac at this time - I did my photo edits last night.

The ambient temperature in this room is now 35.4 degrees. Mac specis say max 
ambient temp for a Mac is 30 degrees. Unless the internal fan is running flat 
out (and noisy!) then I would just let the Mac have a sleep for a while.  The 
aluminium case is really a heat sink and the heat must transfer to a cooler 
external environment. Internal heat sensors should get the fan to work faster - 
and it can really hot inside.

A problem with apps to monitor (and adjust) fan speed is that many people  
“fiddle” with the settings.  Then discover the basic problem was clogged  air 
vents that can be cleaned without dismantling the computer.

Perhaps a small personal fan blowing across the back of the iMac would help 
move the heat away.  Dipping in water is NOT recommended!

Just my opinion.

Cheers,
Alan

Tony,

I had the same problem, and installed smcFanControl to monitor the fans. It 
lets you check the temperature on CPU and HHD. After a couple of weeks I 
decided that the problem was with my CPU fan, and that it was probably an 
accumulation of dust - the machine is some years old. I took it into our local 
service centre and had it cleaned out - it has been just fine for over a year 
now.

IMac problem.

[Anthony (Tony) Francis]

Good Afternoon Everyone

I am having a problem with my iMac 27” running extremely hot, I seem to 
remember a query by another member some time ago with the same problem. After 1 
hour of processing Photo’s the rear of the Computer is almost too hot to touch, 
how do I check the Fans or will I need to remove the back and possibly clean 
the inside of the Computer?

Thanks Guy’s

Hi there,
I thought I explained that I  did already boot to Recovery and re-installed
high sierra but it made no difference.

Yeah...the lack of backup is going to be ...difficult.
My husband’s uncle didn’t consider it at all.

Lesson learned I hope

Re: iMac problem

Hello Rosemary,

Did you actually get through with Command + R? 
You can do a recovery which basically reinstalls OS X but keeps your files in 
tact.
 It's kind of like Windows system restore.

If that fails and ‘NOT having a backup’ … could be a hard lesson learnt!

iMac Problem

[Warwick L Smith]

Hi all

My nephew has an older 20 iMac that has been giving him problems for some 
time, and is now starting to hang randomly. Disk utility fixed a few minor 
problems, but revealed nothing crucial.

A hardware test from the original MacOSX 10.4 disk  reveals an error code 
4MOT/2/4004:HDD - which a Google search suggests may be a hard disk fan 
motor problem rather than a disk problem (but this is not very clear).  

Has anyone else encountered this problem locally and found a viable solution?  

Thanks

Warwick

Re: iMac Problem

[Craig Bruce]

The error code mentioned is a fan sensor failure, the fan could still but 
running but would need to test on the bench. Would require either a new fan or 
a new logic board depending where the issue stems from, The hangs would be from 
the drive getting hot due to lack of cooling

Re: iMac Problem - hardware?

The problem has been fixed - it was a faulty hard drive that was  
messing up the whole system. Thanks to the Joondalup store for  
sorting this out and organising the replacement.

iMac Problem - hardware?

[Mike Fuller]

I was asked to check a relative's Mac today - iMac 17 G5 running OSX  
10.3.9 - because it wasn't working as they'd like.


I found:
Standard boot took at least 5 minutes most of which was on the grey  
apple screen with the circular timer

it didn't recognise the disc in it, even though there wasn't one there.

Same if a flash drive was attached via USB
Same if a firewire optical drive was attached
If a disc was inserted into the firewire drive Toast could read or  
write but the system either couldn't read it or it ignored it


Most interestingly, a safe boot holding the shift key always led to a  
kernel panic and a hung computer, on the grey apple screen before it  
reached the circular timer. This was with only the keyboard and mouse  
attached.

Un unsafe boot just took a long time but reached the finder screen.

I checked the ram, swapping them out independently, but the same  
symptoms occurred.


I did all the regular bits like refreshing PRAM, repairing  
permissions etc. There was about 7GB free on a 74GB hard drive.


I couldn't boot up with a system DVD or CD because it wasn't  
recognised, even when booting while holding the C key, so I couldn't  
check the boot drive with Disk Repair.


I suspect there is an element of hardware failure here but I would  
appreciate any input as to what could be the problem and how it  
possibly could be fixed.


Thank you

You  have another alternative to boot from Cd/DVD

If you can  get DVD in the optical drive , power down then :-

Hold down the option key immediately when you Power on and wait for  
arrows


to come up   plus   hopefully choices of system and DVD operating  
systems.

And if you can do that you should also be able to run Apple Hardware Test:

 For PPC based Macs, use the Install Disc 1 that came with your Mac, hold down
 alt or option key depending on your keyboard, select the Hardware Test from
 the menu, and the menu selections and loop mode are as for Intel based Macs.

Though there seems to be some doubt as to how well it actually shows up
faults, for example my 24 iMac just had the video card replaced under
warranty, but hardware test had not shown up any problems!

General consensus seems to be - if it says you have a problem then you most
likely have a problem - however, if it says you don't - well, you still may
have a problem!

Still, if you can get it to run it may give you some info.

Thanks for those suggestions, Bob and Neil. I can't run the Option/ 
Alt test at present because I don't have that computer available but  
I will get the owner to try it in the next day or two.


However, considering the system wouldn't acknowledge the optical  
drive when holding the C key at boot up, and wouldn't eject the disc  
by holding the mouse button on boot up or boot down (such a term?) I  
suspect that strategy may not work.


What I find most disturbing is the kernel panic in safe boot mode.  
What is it doing differently, at such an early part of the boot up,  
from what it would be doing in standard boot?


Cheers

Mike Fuller

2001 iMac problem

[Manzie Greg]

Hello WAMUGgers

We are having issues with an iMac upgrade where there may be a  
corrupted hard drive.


2001 Snow G3 iMac, 20gb drive 500GHz

Was running 10.2.5 but not seeing some external drives.

Not had permissions repaired for years. No DiskWarrior or any system  
maintenance for years.


Needs to be upgraded for new internet connections

Tried to update to 10.3 via archive and install, installation failed  
at verification stage a few times.


Noticed that firmware was at 4.1.7 and recommended is 4.1.9. Ran  
update but OS9 said OS 10 cannot be updated from there. Firmware still  
at 4.1.7.


Disk utilites failed to repair disk and fully repair permissions.

DiskWarrior 3.0.3 failed to create graph and could not repair disk.

Problem seems to be some old obsolete Lexmark files. The Lexmark  
printer had severe problems some years ago and was ditched.


After zapping the PRAM a few times the problem persisted.

Then deleted some OS 9 classic files (wrong).

Now the machine no longer boots up from CD of any kind, though holding  
the mouse button ejects CD's OK.


Holding C, X, or shift key makes no difference.

Won't see OS 8.6,  9.1, 10, or DiskWarrior CD. Just comes up with gray  
apple (OS 10 on the internal drive I suspect). Then freezes.


Using programmers button brings up terminal, but I do not know what to  
do in terminal.


Zapping PRAM again no good.

Machine too old to boot up using T key.

If anyone has any suggestions, we would appreciate your help please.

Re: 2001 iMac problem

[Manzie Greg]

Robert, thank you so much.

The option key worked and after a bit of juggling I have managed to  
get the 10.3 install CD to work.


Now I will try a clean install and let you all know how I get on (will  
be tomorrow now).


I already asked about the battery and my friend is going to purchase a  
new one. It's so old it's bound to be exhausted.


Regards

It might help the whole picture if your internal battery was  
renewed ...  you don't say anything about it

Is it good or is it old and bad ?

There is one other choice you did not mention . hold down option  
key immediately after power on .
If you manage to keep a CD in the works while you power up it may be  
shown as a choice to boot from .


Resetting firmware may be a possibility but I need to research that  
for your model


Bob

And here is the research   hope you have not got the bad bit !
