System restore for Mac?

Does it exist?
How does one operate it?

Also keep in mind that you can only boot Intel Macs from a USB drive.
I don't know if perhaps booting an Intel Mac from a FireWire is just not supported, but I can testify that it's most certainly possible. I'm making this post on my MacBook Pro while booted from the clone of the MBP hard drive on my FireWire drive.  
Looking around, I find this: Firmware update for Intel-based Mac does not install with non-GUID partition scheme, which peripherally mentions booting Intel Macs from a FireWire drive:
Option 1: Use an external startup disk
If you have a bootable external disk, such as a FireWire disk, that is configured with the correct partition scheme (GUIDpartitionscheme), start up from it using Startup Disk preferences, then apply the firmware update during start up.
That certainly indicates it's supported, since they're suggesting starting up from an Intel Mac from a FireWire drive.
I haven't come across anything from Apple, other than the above, saying one thing or the other about Intel Macs being bootable from FireWire. Does anyone else have a link - something saying that it is or isn't supported?

    How to maintain a Mac
    1. Make redundant backups, keeping at least one off site at all times. One backup is not enough. Don’t back up your backups; make them independent of each other. Don’t rely completely on any single backup method, such as Time Machine. If you get an indication that a backup has failed, don't ignore it.
    2. Keep your software up to date. In the Software Update preference pane, you can configure automatic notifications of updates to OS X and other Mac App Store products. Some third-party applications from other sources have a similar feature, if you don’t mind letting them phone home. Otherwise you have to check yourself on a regular basis. This is especially important for complex software that modifies the operating system, such as device drivers. Before installing any Apple update, you must check that all such modifications that you use are compatible.
    3. Don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” "boosters," “extenders,” “cleaners,” "doctors," "tune-ups," “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this stuff is useless, or worse than useless. Above all, avoid any software that purports to change the look and feel of the user interface.
    The more actively promoted the product, the more likely it is to be garbage. The most extreme example is the “MacKeeper” scam.
    As a rule, the only software you should install is that which directly enables you to do the things you use a computer for — such as creating, communicating, and playing — and does not modify the way other software works. Use your computer; don't fuss with it.
    Safari extensions, and perhaps the equivalent for other web browsers, are a partial exception to the above rule. Most are safe, and they're easy to get rid of if they don't work. Some may cause the browser to crash or otherwise malfunction.  Some are malicious. Use with caution, and install only well-known extensions from relatively trustworthy sources, such as the Safari Extensions Gallery.
    Never install any third-party software unless you know how to uninstall it. Otherwise you may create problems that are very hard to solve.
    4. Beware of trojans. A trojan is malicious software (“malware”) that the user is duped into installing voluntarily. Such attacks were rare on the Mac platform until sometime in 2011, but are now increasingly common, and increasingly dangerous.
    There is some built-in protection against downloading malware, but you can’t rely on it — the attackers are always at least one day ahead of the defense. You can’t rely on third-party protection either. What you can rely on is common-sense awareness — not paranoia, which only makes you more vulnerable.
    Never install software from an untrustworthy or unknown source. If in doubt, do some research. Any website that prompts you to install a “codec” or “plugin” that comes from the same site, or an unknown site, is untrustworthy. Software with a corporate brand, such as Adobe Flash Player, must be acquired directly from the developer. No intermediary is acceptable, and don’t trust links unless you know how to parse them. Any file that is automatically downloaded from a web page without your having requested it should go straight into the Trash. A website that claims you have a “virus,” or that anything else is wrong with your computer, is rogue.
    In OS X 10.7.5 or later, downloaded applications and Installer packages that have not been digitally signed by a developer registered with Apple are blocked from loading by default. The block can be overridden, but think carefully before you do so.
    Because of recurring security issues in Java, it’s best to disable it in your web browsers, if it’s installed. Few websites have Java content nowadays, so you won’t be missing much. This action is mandatory if you’re running any version of OS X older than 10.6.8 with the latest Java update. Note: Java has nothing to do with JavaScript, despite the similar names. Don't install Java unless you're sure you need it. Most people don't.
    5. Don't fill up your boot volume. A common mistake is adding more and more large files to your home folder until you start to get warnings that you're out of space, which may be followed in short order by a boot failure. This is more prone to happen on the newer Macs that come with an internal SSD instead of the traditional hard drive. The drive can be very nearly full before you become aware of the problem. While it's not true that you should or must keep any particular percentage of space free, you should monitor your storage consumption and make sure you're not in immediate danger of using it up. According to Apple documentation, you need at least 9 GB of free space on the startup volume for normal operation.
    If storage space is running low, use a tool such as the free application OmniDiskSweeper to explore your volume and find out what's taking up the most space. Move rarely-used large files to secondary storage.
    6. Relax, don’t do it. Besides the above, no routine maintenance is necessary or beneficial for the vast majority of users; specifically not “cleaning caches,” “zapping the PRAM,” "resetting the SMC," “rebuilding the directory,” "defragmenting the drive," “running periodic scripts,” “dumping logs,” "deleting temp files," “scanning for viruses,” "purging memory," "checking for bad blocks," "testing the hardware," or “repairing permissions.” Such measures are either completely pointless or are useful only for solving problems, not for prevention.
    The very height of futility is running an expensive third-party application called “Disk Warrior” when nothing is wrong, or even when something is wrong and you have backups, which you must have. Disk Warrior is a data-salvage tool, not a maintenance tool, and you will never need it if your backups are adequate. Don’t waste money on it or anything like it.

  • HT4949 what are the system requirements for mac os x 10.6 server?

    what are the system requirements for mac os x 10.6 server?

    While not 'intended', it is indeed possible on a portable. Exigent circumstances required me to re-role an aging MacBook Pro 2.16 Intel Core Duo to act as a server on a temporary basis.
    It boots just fine from an external drive running Server 10.6.8. I also believe that installation (while not recommended) is not actually blocked.
    Tip for the top: just be sure to pull the battery out of the laptop (assuming that's possible) to avoid turning your battery into a grossly distended, non-functional brick... they were not designed to be left on charge permanently!

    Hi,
    You can reinstall them from Recovery Manager by clicking on Start=> All Programs.
    If you have performed a complete HP Recovery using F11 then all the software should be there. If you have performed a minimized recovery then you can install applications from recovery manager...If none of these works then you'll need USB recovery..
    Here are the links that will guide you through the process:

  • System Restore on Mac

    Hello All,
    I'm a recent convert to Mac and was wondering if there's a Mac equivilant to System Restore on the PC. It often came in handy when I downloaded or installed something I regretted.
    Thanks,
    Jim

    Will,
    Time Machine backups are not bootable, but using the Install DVD you can recover your system's contents as outlined in Recovering your entire system
    If you install something, there's no magical way of bringing your computer back to a point before you installed it.
    According to Restoring from Time Machine, by James Duncan Daivdson..."Once you've selected your Time Machine volume, you can select which snapshot to restore from. This is pretty nifty really, tho in most cases, you'll probably want the most recent."

  • Norton System Works For Mac

    Have just upgraded to Tiger and am getting a message that the Norton Anti Virus Auto protect can't proceed, so reinstall and restart. Have done that but makes no difference - I still get the message. Am I missing something?

    Norton BAD. If you feel you need an anti-virus program try the free ClamXav.
    I don't use one since there are no viruses for Macs. Anti-virus programs can slow down a Mac too.

  • Sudden system crashes for Mac mini 2011

    I just came home from a 2-week vacation and my computer has begun to crash and reboot, seemingly when I need the computer to do some task more intensive than Internet browsing.
    It started when I tried uploading pictures into iPhoto via my camera's SD card--and it invariably happens whenever I try this--but it has also crashed and rebooted during simple multitasking procedures, like clicking to check my download progress in Safari as my iPhone is syncing in iTunes. Yesterday I had to contend with the white (grey?) screen of death for a few hours as I tried different methods. Fiddling around in Safe Mode let me fix that problem, at least, but the sudden system crashes still persist.
    Could my computer have been affected by a lack of use over the last two weeks in the summer heat? It's been hot in the house, but not exceptionally so for August. And before I left I shut it down and unplugged the power cord.
    Here are the first several dozen lines of the error report from the most recent crash. If anyone could offer me some help, I'd be very grateful.

    Remove the "MacKeeper" crapware as follows, then reboot and test. If there's no improvement, post again.
    Note: These instructions apply to the version of the product that I downloaded and tested in early 2012. I can't be sure that they apply to other versions, nor do I intend to repeat the test.
    IMPORTANT: "MacKeeper" has what the developer calls an “encryption” feature. In my tests, I didn't try to verify what this feature really does. If you used it to “encrypt” any of your files, “decrypt” them before you uninstall, or (preferably) restore the files from backups made before they were “encrypted.” As the developer is not trustworthy, you should assume that the "decrypted" files are corrupt unless proven otherwise.
    In the Finder, select Go ▹ Applications from the menu bar, or press the key combination shift-command-A. The "MacKeeper" application is in the folder that opens. Quit it if it's running, then drag it to the Trash. A dialog will pop up asking why you want to uninstall it. You don't have to provide that information. Enter anything you like in the text box, then click the Uninstall button. All the functional components of the software will be deleted. That's the only useful feature of "MacKeeper:" it deletes itself. Reboot.
    Do not try to uninstall by dragging the MacKeeper icon in the Dock or the LaunchPad to the Trash.
    Here are some general suggestions. If you want your computer to be usable, don't install crapware, such as “themes,” "haxies," “add-ons,” “toolbars,” “enhancers," “optimizers,” “accelerators,” “extenders,” “cleaners,” “defragmenters,” “firewalls,” "barriers," “guardians,” “defenders,” “protectors,” most “plugins,” commercial "virus scanners,” "disk tools," or "utilities." With very few exceptions, this kind of material is useless, or worse than useless.

  • Scratch install vs. system restore for HA system

    Hi All,
    We are planning for a Mimix High Availability install and would like to know whether our initial install of the HA systems (R/3 in one LPAR and CRM/BW in another LPAR) should be full DR type restore or a new install of R/3, CRM, and BW.  Lakeview has recommended a scratch install and we have a vague memory that change the server name on an already installed SAP system can cause problems.  What type of install did you perform during your initial setup of the HA systems?  Did you load your production database on the HA systems during the initial install or wait until you were ready to start replication?
    TIA,
    Stan

    Hi Stan,
    as Mimix "only" replicates the DB, a few libs and the IFS (or even not) and nothing of the rest of the system, I would not go for a full scratch install. I would start with a homogenious systemcopy with special things in it - e.g. my "easy homo copy" and then you need to discuss how you want to start the server with what IP names etc.
    Most likely you want to switch host names - at least the logical hostname. So, the SAP profiles need to be adjusted.
    But, I don't see any benefit (except additional effort) from a scratch install.
    (you should ensure, that the GIDs and UIDs of the users are the same - this makes IFS easier)

  • System requirements for Mac OS X Lion

    Hi,
    Will Mac OS X Lion work on my Leopard 10.5.8, or do I need Snow Leopard 10.6.6 to upgrade to Lion?
    I haven't bought Snow Leopard until now because I've been waiting for the release of Lion, and I just heard that I need Snow Leopard...
    Please tell me it's not true.

    Mac OS X Lion will be available in July as an upgrade to Mac OS X version 10.6 Snow Leopard from the Mac App Store for $29.99 (US). Lion will be the easiest OS X upgrade and at about 4GB, it is the size of an HD movie from the iTunes Store. Mac OS X Lion Server requires Lion and will be available in July from the Mac App Store for $49.99 (US).
    Lion requires an Intel-based Mac with a Core 2 Duo, i3, i5, i7 or Xeon processor and 2GB of RAM, runing the latest version of Snow Leopard. The Lion upgrade can be installed on all your authorized personal Macs.
    The Mac OS X Lion Up-To-Date upgrade is available at no additional charge via the Mac App Store to all customers who purchased a qualifying new Mac system from Apple or an Apple Authorized Reseller on or after June 6, 2011. Users must request their Up-To-Date upgrade within 30 days of purchase of their Mac computer. Customers who purchase a qualifying Mac between June 6, 2011 and the date when Lion is available in the Mac App Store will have 30 days from Lion’s official release date to make a request.

  • System restore for multiple partitions

    Hi guys,
    This is probably an easy question, and I think I have the answer from reading other threads, but I want to make sure I have the right idea before I start reformatting things!
    I want to install linux on a partition of my 500 GB HDD on a T410 currently running windows 7, and I want to create backup disks to:
    a) Get a factory image on my newly sized windows partition (400 GB windows / 100 GB linux) in case I need to reformat the windows partition alone; and
    b( Restore everything to the factory fresh windows only system, the way it shipped, in case I ever want it as all one windows partition again.
    As I understand it (I've never played around with laptop installations before), I need to make a backup partition as soon as I turn on my new laptop, create a recovery DVD from that backup partition, and then I can delete the backup partition.  But that will only work for the factory fresh 500 GB windows installation, so, after I partition the drive, I have to create a new recovery partition to create new recovery DVDs, and then delete that recovery partition.
    If I'm right on all that, I should end up with two sets of recovery DVDs, no recovery partitions (because I've deleted them after making the DVDs), and I can use the set of DVDs that corresponds to the way I have the drive partitioned when I choose to reformat.
    Does all that make sense, or have I missed the boat on any of it?
    Thanks for taking the time to ease my fears before I mess with my new laptop's drives!

  • How do you perform a full system restore for the hp officejet 6500

    Basically, after having this printer for 1 year, the wireless printing started to not work correctly. After buying a laptop and trying to configure the printer with it, the printer started to have problems with wireless printing. So how do you perform a FULL factory reset? I already tried hitting #9 while the printer was turning on but it only seemed to partially reset the system. It did not turn it back to the day i bought the printer.

    OK, so it turns out it was the 'only show synced content' tick box.
    Wow, how embarrassed do I feel now? I never even paid any attention to that tick box all these years.
    Interestingly, over the last couple of days I had my ATV at v1.1 again, and happily deleted all my content (except for 1 album which I deliberately left on). A few days went past, and I checked daily - and there was only ever the 1 album.
    I then upgraded to ATV v3.0.1 again today and that's when my problems came back - all my content magically reappeared on the Apple TV (or so I thought).
    I'm thinking maybe that the 'only show synced content' is a recent 3.0 feature? And if so, maybe that's why I never noticed it before and that's why it was confusing me? Or maybe it's been there all these years (in which case I'll carry on being embarrassed).
    Anyway, a huge thanks to everyone who responded.
