How do I find out how much memory is in an eMac with no hard drive?

I purchased a used old eMac G3 and am a PC guy only. I bought it from someone who told me that there is 512mb of RAM in it, but I want to confirm this. Is there a way to get into the BIOS for eMacs? I just want to find out how to check how much RAM is inside.

Can the drives on them read DVD-RWs? What about dual layer DVDs?
Depends on what that sticker says, assuming the drive has not been replaced. It's hard to say with eMAcs; becasue they were an edu-model, they probably have more optical drive posibilities than any other Mac. Some even shipped with NO optical drive, presumably to prevent students from bring software from home.
The MacTracker database (free from http://mactracker.ca/) lists the following possibilities for optical drives in a 1.25G eMac:
None, CD-ROM, DVD/CD-RW Combo, or 8x SuperDrive
Also more tech info here:
http://www.everymac.com/systems/apple/emac/stats/emac_1.25.html
The combo drive reads DVDs. Reading DVD=RW may depend on where they were burned and the media brand. The next model, the 1.42Ghz, shows the SuperDrive as dual layer; no such entry for the 1.25G.
If you are thinking about burning a system disk from another computer, be aware that almost never works on Macs.

  • How much Ram can my Macbook use?  What Hard drive should I upgrade to?

    Hi Everyone.
    I have a 2008 ish macBook with 4gb of Ram.  I use vmware Fusion to run Windows every day and I also use Aperture on a regular basis.
    I'm looking to breath some life into this old machine and want to know how much ram the motherboard will support.  Here are the machine's specs.
    Hardware Overview:
      Model Name:          MacBook
      Model Identifier:          MacBook4,1
      Processor Name:          Intel Core 2 Duo
      Processor Speed:          2.4 GHz
      Number Of Processors:          1
      Total Number Of Cores:          2
      L2 Cache:          3 MB
      Memory:          4 GB
      Bus Speed:          800 MHz
      Boot ROM Version:          MB41.00C1.B00
    How muck Ram will the machine support? 
    My Hard drive is also nearly full and I would like to upgrade to a 500gb drive.  Any suggestions on which drive to choose?
    Thanks!!

    You can install up to 6 GBs of RAM. There are any number of good choices for a hard drive replacement. I suggest visiting OWC for information on pricing, makes, and models. They also provide video tutorials on how to replace a drive in MacBooks.
    To prepare for the upcoming release of Lion I also suggest spending $29 to buy a Snow Leopard DVD and upgrade your OS.

  • How much space does time machine take up on hard drive?

    Can anyone let me know how much hard drive space time machine takes up?

    Hi, and welcome to the forums.
    Time Machine keeps copies of everything on your system (except a few things like system work files, most caches and logs, and trash), so the first backup will be a bit smaller than the amount of data on your system.
    Subsequent backups will copy things you've added or changed, but doesn't delete the copies of the old versions, or of things you've deleted, so you can restore them if you find you've deleted or changed something in error, or something has gotten corrupted. Thus Time Machine will need considerably more space. IIn most cases, it won't delete it's copies until it runs out of room.
    It varies depending on how you use your Mac, but a "rule of thumb" is, it needs 2-3 times the space of the data it's backing-up to be able to keep a reasonable "depth" of backups for you.
    You might want to review the [Time Machine Tutorial|http://www.apple.com/findouthow/mac/#timemachinebasics] and perhaps browse [Time Machine - Frequently Asked Questions|http://web.me.com/pondini/Time_Machine/FAQ.html] (or use the link in *User Tips* at the top of the +Time Machine+ forum).

  • How to set up One iTunes Library with Multiple Hard Drives

    Hello,
    I have a question about setting up a daisy chain of external storage hard drives for my itunes library and need some advice.  I have run out of room on my 4TB external storage.  I have an additional 4TB and a 2TB external storage (all are MyBooks) and trying to figure out how to separate out my itunes folder:  I would like to put the TV on one 4TB and the Movies and the other 4TB and the Music/Apps/etc on the 2TB.  Here are my questions
    1.) How to I point my iTunes to where I have moved them?  Just make and alias of the folder and put that back in the original folder?
    2.) How do I get the new iTunes downloads to go the correct folder to download so it does not set up a new library for downloading?  Can I set more that one location in my preference?  If so- how?
    I have looked in the forums and all the information is older and does not address this exact issue. 
    Set up:
    Mac mini hooked up to Vizio TV running Lion 10.7.2
          Processor 2.26 GHZ Intel Core Duo 2
         Memory 4GB ( do not really store anything on this one)
    MY Books
         1  2TB   Mac OS Extended (Journaled)
         2  4TB   Mac OS Extended (Journaled)
         1  1TB   Mac OS Extended (Journaled)-  this is for documents, etc
    All these are daisy chain with 800 Firewire to the Macmini and hooked to TV with HDMI.
    Any suggestions would be helpful.  I can not download anything else from iTunes until I get this resolved and it is a real bummer.

    When syncing contacts, you can choose to sync all of your contacts or only selected groups.
    You can select a group of contacts to which all new contacts created on your iOS device will be added.
    You can set up groups in the Address Book application.
    If you are all going to use the same iTunes apps library, turn off "Automatically sync new apps" in the apps tab just below the list of apps.  Then you won't get new apps on your device unless you select them.

  • How to  back up Final Cut project with external hard drive. Absolute beginner, so simple steps appreciated.

    Hello - How do I back up a Final Cut pro project onto an external hard drive?  It's a work in progress, not a completed project. I'm a total beginner and a step by step would really helpThanks

    BenB wrote:
    The auto-backup is the database only, not the media.
    To back up the whole Library totally, first make sure to Consolidate it, then simply drag-and-drop it on to the backup drive, that simple.
    The KB article referenced by Karsten suggests one additional step: make sure your copy of the library is not at the root level of the drive to which you are copying it. I have not clue why this might be important.
    Herewith:
    Back up your Project Library and events using the Finder
    To create a single backup copy of your Project Library and events, you can copy the Final Cut Projects folder and Final Cut Events folder to an external storage device.
    If you are backing up incrementally, create a folder structure that helps you easily navigate through your backup folders. You could label the folders with the date you made the backup copy, for example.
    Important:    To avoid issues, it’s essential that you place the backup files in a folder (named “2012 Final Cut Pro Backups,” for example) that is not at the root level of your external storage device.  
    In the Finder, locate and select your Final Cut Projects folder and Final Cut Events folder.Your Movies folder is the default location for all project and event files:/Users/username/Movies/ Important:    If you moved a project or event after you created it, it will not be in the default location.
    Drag the Final Cut Projects and Final Cut Events folders to the external storage device.
    The folders are copied to your external storage device.

  • How best to setup a Mac Pro with two hard drives for 1st hard drive or OS failure?

    My first Apple, a Mac Pro,  is to arrive on Monday (1/7).  I will be putting Win7 on Bootcamp and installing Parrallels.  It will have two 1T hard drives.   I would appreciate
    any advice on how best to set it up for best recovery in case of a hard drive or OS crash.   You can tell I have experience with Windows.    It looks like my best choices are
    either disk cloning software or just installing OS X from the recovery disk  on the second drive.   Apple says it is legal to do another installation.   I know the disk cloning will not work on the bootcamp partition which I plan to use for the Parallels program.  Can OS X have an option to boot from two differnet disks and OS installs?
    What I am really wanting to do in the event of a crash,  is to just boot up on the other disk and keep working.     I try to keep data on a separate partition  with backups so
    that a disk or OS crash doesn't cause any data loss.

    I do not use windows.
    However on my Mac Pro for cloning/backups/bootable backups i use Carbon Copy Cloner.
    It has an ability to clone entire disk (unless specified differently) so I can boot from another disk or restore back if I want to.

  • How to configure iPhoto in my setup with external hard drive

    Hi there,
    I've been digging around for answers but I'm still not clear on what the right path is.
    I have a new MacBook Air. For the obvious reason (space) I don't want to keep my photos on it. I have a functioning MacBook with a dead backlit screen. I can run it easily with an extended monitor.  I have a new 2 Terrabyte Seagate Go Flex Home external drive that is my Time Machine backup. 
    I'm thinking that I should be able to have all my photos on the external hard drive and access them from my MacBook Air.   But I don't know what the "best" or "easiest" or good route is to follow. 
    1) Can I move the my current MacBook iphoto library to the external Seagate Go Flex HD? ? There's an issue of the right formatting, yes? How would I know?
    2) Should I skip using Iphoto and simply store photos? I don't love that idea.
    3) Should I keep my old photos on the MacBook and access them from my Macbook Air? I have a 500 gig drive on that machine.  If so, I need to make sure it never goes to sleep, yes?
    4) If I do that can I set up the Air so that the photos go tot he MacBook?
    4) Macbook has iPhoto '08. The Air has iPhoto '11. Is that an issue?
    Is this all easier than I'm thinking? Or is is complicated?
    THanks for your help,

    You can move your iPhoto library to any directly connected hard drive that is formatted Mac OS extended (Journaled)
    You can NOT share a single volume between a Time Machine backup and any other dynamic files ike the iPhoto library - TM continues to fill the drive until it is full and at that time iPhoto would quit working
    You can not share a library with different versions of iPhoto
    IMHO using a MBP as the drive for a MBA wouod not work well and might cause problems
    My suggestion is to move your liberary to a new external drive -
    Moving the iPhoto library is safe and simple - quit iPhoto and drag the iPhoto library intact as a single entity to the external drive - depress the option key and launch iPhoto using the "select library" option to point to the new location on the external drive - fully test it and then trash the old library on the internal drive (test one more time prior to emptying the trash)
    And be sure that the External drive is formatted Mac OS extended (journaled) (iPhoto does not work with drives with other formats) and that it is always available prior to launching iPhoto
    And backup soon and often - having your iPhoto library on an external drive is not a backup and if you are using Time Machine you need to check and be sure that TM is backing up your external drive
    And create a new library on your MBA for protable use and for current photos and use iPhoto Library Manager - http://www.fatcatsoftware.com/iplm/ -  to move photos between the iPhoto library on the EHD and the MBA

    I have an iMac g3 grafite se, the person before me forgot their admin password so I bought a new hard drive for it but I don't know how to re install the software I turned the iMac on and I just had a grey blank screen would really appreciate some help please I have an iMac software install disc which say Mac OS version 9.1, I have iMac applications cd, all 4 iMac software restore discs and they say Mac OS version 9.1 , 10.0.3 and a Mac OS X version 10.0.3

    I have iMac applications cd, all 4 iMac software restore discs and they say Mac OS version 9.1 ,
    Boot from the gray system restore disk marked "Disk 1" by inserting the disk and then restarting while holding the C key. It takes a couple of minutes to boot from a CD or DVD but, when complete, you will have access to an installer. I'd install OS9 first to see if the comptuer works.

  • Where can I see how much space mac mail is taking on my hard drive?

    I have a gmail, yahoo mail and icloud mail that I access on Mac Mail.  Does it take up much space on the HD?  I'm assuming they are all stored on the web servers but where do I look on the Mac to find what space they are taking up on my Mac?

    In the Finder, hold the Option key and then choose Library from the Go menu. Then locate the folder called "Mail," and get information on it and note the calculated size. In addition, do the same for the Mail Downloads folder, and these two should constitue the majority of the space used by Mail and its configured accounts.

  • How do I synch my iTunes library with my hard drive?

    Hello,
    I am relatively new to using the iPod and iTunes. I have recently added and deleted music files on my hard drive, but this is not automaticallly reflected in my iTunes library. Is there a way to have the iTunes library automatically sync with what is on the hard drive? Thank you!

    You'll have to add your music back in to iTunes manually by either dragging the folder your music is in to the iTunes source list or by using the File>Add file or Add Folder to library function: About the Add to Library, Import and Convert functions

    smash adams,
    If you're talking about hard disk space, open Finder, click once on your hard disk (left column) and look at the bottom of the Finder window.
    If you're talking about RAM, Finder >Applications > Utilities > Activity Monitor.
    Open Activity monitor and click the System Memory tab.
