Can I leave an iMac running without rebooting for an extended period?

A month ago I bought a new iMac to replace an old one, which I used for Logic Pro and as a home media server -- it ran great for years (mostly Plex with a few scripts running through the day and night).
I had a few issues with the new iMac hanging and rebooting into safe mode by itself, so I took it back to the Apple Store and chatted with an Apple Genius. He ran some diagnostics and found no hardware issues, and so he did a fresh install of OS X.
One bit of advice he gave me was to make sure that I reboot the machine at least weekly.
I used to be a System Engineer at Sun Microsystems. When we ran our systems as servers we rarely rebooted them, often leaving them for months, and in some cases years. So it was a bit of a surprise that he recommended this.
He suggested this was so fsck could run to keep the file system clean.
Am I right in thinking that the iMac shouldn't need rebooting that often to keep it running well, and it certainly shouldn't cause it to hang or crash the whole OS? Any thoughts or experiences welcome.

It doesn't need to be rebooted every if it's maintained correctly. Many have theirs on for weeks and months only restarting when required to install software.

You could buy an external dvd/cd drive.
Suggest other world computing.
You need to delete some files. Many posters to these forums state that you need much more free space: 5 gig to 10 gig or 10 percent of you hd size.

Be careful when deleting files. A lot of people have trashed their system when deleting things. Place things in trash. Reboot & run your applications. Empty trash.
Go after large files that you have created & know what they are. Do not delete small files that are in a folder you do not know what the folder is for. Anything that is less than a megabyte is a small file these days.

Can I use my iMac as a 'display' for my MacBook Pro?

Hi all, I am really hoping someone can help me here.
I am wondering if I can use my 24" iMac as a display for my MacBook Pro (both running Snow Leopard).
It's my father's 80th birthday party in about 24 hours time. I am doing up the music and slideshow (thanks Apple - so easy!).
My plan was to simply take my iMac and use it. However, I managed to drop the wireless keyboard (darn those dogs) and now my keyboard won't work. I have no backup keyboards here (gave the wired one to Dad to use with his Mac mini). I live in a country area with no access to a Mac store and it will take more than 24 hours to get a new one. Went to my local 'other computer' general store last night: I really don't want to buy an ugly black keyboard..... I have just had a great idea:
Can I network my MacBook Pro and use it as the source for the slide show and simply use the iMac as a display? I have plenty of DVI adaptors but am just not sure how I would go about the software side of things? Or should I simply buy an ugly PC keyboard (and if I do, will the WIndows button work as an Apple button???)
Any suggestions would be really appreciated.
Thanks!

The imac 24 can't be used as a monitor over a DVI connection or the like, Suzanne, but you may be able to achieve what you want to using "Screen Sharing" by networking the two computers. This lets your MBP effectively control what is running on the iMac.
See HERE for the basic setup. For information about how to access the "shareable" screen from the MBP see HERE.
One possible problem may be actually getting this set-up on the iMac if it is not already enabled, however, unless you can borrow a keyboard from someone (your password may have to be entered to enable it). You may be able to get around this, if necessary, using the "keyboard viewer" (which you can place in the menubar using System preferences > Keyboard, if you don't already have it there).

Can I use my Imac as a monitor for my Macbook Air?

Can I use my iMac as a monitor for my Macbook Air?

Without any knowledge of the year machines you have it's impossible to answer that question. iMacs adn MBA's have been around for many years now so we have no idea of the exact specs your machine have. Remember when posting you need to be complete and paint a picture for us as we aren't there to look for ourselves. Your question should be posted something like:
" I have a 2011 27" iMac and a 2009 MacBook Air, can I use the iMac as an external display for my MacBook Air?"
BTW what you are referring to is called Target Display Mode. Apple does support that on some 2009-2011 iMacs. You can find additional information at:

You need to find out what video out you have on your iMac, and what kind of video inputs there are on your TV.
It will help to know exactly what model iMac and exactly what make/model TV you have.
Depending on the exact model iMac you have, it may have miniVGA, miniDVI, miniDisplayPort or Thunderbolt output. Your TV may have composite, S-video, component, DVI, VGA or HDMI inputs. Once you confirm what kind of ports your iMac and TV have, then we can probably suggest the correct cable or adapter so you can connect them to each other.

I have two computer one being a new mac book pro and the other being a slightly older imac desktop. I am wanting to know if you can use the desktop as a screen for my mac book pro.

Is this possible and what connections do I need?
Thanks

Can you fix , the fact that If you leave the firefox update window open for a long period (say 20 minutes in the background), then close all other windowns, then choose to install, it uses this extra time to estimate the download?

Can you fix , the fact that If you leave the firefox UPDATE window open for a long period (say 20 minutes in the background), then close all other windows, then choose to download update, it uses this extra time to estimate the download? (Mine said, 12 Hours to start with, but took under 2 minutes!)
== This happened ==
Not sure how often
== When you install update to 3.6.4 (Possibly for every update?)

The download should happen in the background (before you get an update window). I wonder why that didn't happen for you...\
Did you manually check for updates?

What do I need to worry about when running a VI for an extended amount of time?

Hi, I'm fairly new to LabVIEW as a program, but not new to programming as a whole.
I'm attempting to build a VI which will, hopefully, be run continuously and take data for weeks-months at a time.
I've never built a VI, let alone a program, which will be run continuously for so long, and so I'm unsure as to what I should be concerned about. I'm looking right now at optimizing, as best I can, memory allocation, algorithms, etc. but I suppose my main question is: What should I really be worrying about when programming a VI which will be run continuously for an extended period of time?
Solved!
Go to Solution.

In the structure of your VI's, be certain that you are not repetively creating things such as references to queues, or file references, or DAQ tasks, or anything without closing them. I was working on one application where a DAQ task was getting created every loop iteration and not being closed. It crashed the PC hard with a blue screen of death after about 20 minutes of operation, through debugging and before I found the cause, I saw I had about 80,000 to 100,000 iterations of a loop fairly consistently before the crash.
If this loop had run at a slower rate, it might have taken days or weeks before the PC would have crashed. It would have seemed infrequent and would have taken longer to debug because I would never have seent the pattern. If it takes a few failures before you discover the problem, it is a lot quicker to find the explanation after a few failures at 20 minutes per failure as opposed to 20 days per failure. The problem was eventually found in a subVI several layers down and fixed.
So if you pay attention to these things early enough, then hopefully they won't pop up and bite you weeks or months into a critical run of the program.

In oneasset class i have created 2 assets by using of aso1 after that i acquired one asset for that i run the depreciation for first 5 periods, it has been showing depreciation for those period but if i am trying to run the depreciation for second asset i

in on asset class i have created 2 assets by using of aso1 after that i acquired one asset for that i run the depreciation for first 5 periods, it has been showing depreciation for those period but if i am trying to run the depreciation for second asset it is not showing first 5 periods why it is not showing? Is there any reason?

Hi
Repeat run you can do only for the last depreciation period. For the asset which you are tryin to post depreciation from July to Jan, please check the asset value date which you have given while posting the transactions or in the asset master.
If the asset value date is in July, then deprecaition from July - Jan will get posted in the current month depreciation in total. You will not be able to post depreciation individually month wise using AFAB.

When working in the basement for an extended period I get SOS message and have to turn my phone off and on before I can use it is this normal

When working in the basement for an extended period I get SOS message and have to turn my phone off and on before I can use it is this normal

when the phone detects the Optus network, this will automatically go out of the SOS mode.
The SOS mode allows you to call SOS numbers like 911 or 112 even if there is no network coverage.
What it does it tap to the next available carrier (regardless if this is your home carrier or not) to have the emergency call pushed through)

How can i get my Imac, running OSX 10.6.8 with a 2Ghz Intel Core 2 Duo, how can i get Final Cut Pro 4 and DVD studio pro 2 to run on it?

I just bought an IMAC running OSX 10.6.8 (not sure what flavor that is). The processor is 2Ghz Intel Core 2 Duo (Late 2006). When i run Final Cut Pro 4 on it I get the following error.
                    "Configuration error
                       This software requires certain hardware or software which is missing
                                * AGP graphics Card"
If Final Cut Pro 4 doesn't run on my system, what version of Final Cut can I run on this as I am a filmmaker and really am comfortable with Final Cut Pro.
On the same note I also have DVD studio Pro 2 and that just quits without any message.
Hope any of you can be some help.
Thank you,
Doug

This is my first mac in a long time so i'm not sure about what this mac is as i didn't buy this from apple (ala Amazon). I'm a tad confused about the Intel/PowerPC thing. I do know the software version for sure, but the Intel/PowerPC is very confusing. I just need to find someone who would know about this question. It doesn't say G5 on this computer. Thats my biggest confusion. Help Me...
