system defrag trial software / shareware for mac

Every computer user has noticed it; over time, your system slows down. This is particularly true in these days of constant security updates as replacing operating system components not only increases the potential for file fragmentation, but also creates a more insidious problem over time, the operating system itself ends up scattered all over your disk.
This, of course, doesnt show up as fragmentation after all, the files themselves are probably contiguous but nevertheless, it takes your machine longer to start up, it takes programs longer to start, and above all, it takes longer to get your work done.
iDefrag defragments and optimizes your disk for improved performance.
Add in the size of some of the files in common use today, especially music, video, graphics and computer games, and even the best filesystem has trouble keeping things contiguous.
Some people say that HFS+ is so good that you dont need to defragment. In a way, theyre right: HFS+ is pretty good at keeping small to medium sized files from getting fragmented it isnt particular good, however, at keeping large files or free space from fragmenting, a particular problem on the Mac because the swapfile must be contiguous on the disk, so you can actually run out of virtual memory long before you run out of disk space if your free space is fragmented.
Another objection, this time raised by Apple, is that existing defragmentation tools may actually slow your machine down by moving files into or out of the "Hot Band", defeating Panthers Adaptive Hot File Clustering code. As far as we know, iDefrag is the first defragmentation tool for the Mac that fully supports the Hot Zone, guaranteeing that this is not a problem.
Even if you arent interested in defragmenting your hard disk, if you produce products on CD-ROM disks, iDefrag will be of use. Seek times on CD-ROM and DVD-ROM disks are many times slower than those of hard disk mechanisms, so fragmentation really hits performance, in some cases adding many minutes to read times. iDefrag can defragment disk images before they are burnt onto CD or DVD-ROM, optimizing access time and significantly reducing install or read times.
And, unlike other products, iDefrag provides a wealth of information about your files, so you can see which ones are most fragmented and even look where they are on the disk. The screenshots on this page are from a perfectly normal 120GB hard disk, installed in a PowerMac G4 that is used for software development, wordprocessing and other everyday tasks (writing this web page, for instance).
Look how fragmented it has become; most of that is actually down to one or two large files, like /usr/bin/emacs, shown on the right, with 96 fragments but there are a substantial number of less fragmented files, over 3,000 in fact.
Main features:
- Full support for Mac OS X 10.5 Leopard
iDefrag is compatible with the latest versions of Mac OS X, and with the very latest hardware from Apple.
- Works with Time Machine
iDefrag is safe to use on Time Machine back-up volumes if you so wish.
- Native support for journaled filesystems
iDefrag knows about the journal and does the right thing automatically. No need to turn journaling off to defragment or optimize your disk.
- Support for case-sensitive HFS+
Using case-sensitive HFS+ for compatibility with legacy UNIX software? No problem. iDefrag knows what to do.
- Supports the Hot Zone
Mac OS X is smart about the files you use the most. It moves them to an area on the disk called the Hot Zone, for improved access times. Unlike older defragmentation tools, iDefrag understands the Hot Zone, and knows which files should be there.
- Thermal Monitoring
iDefrag watches the temperature of your disk while defragmenting. If things are getting a little toasty, iDefrag will wait for the disk to cool down before continuing.
- Four powerful defragmentation algorithms
Optimize or compact your disk as required. Includes a sophisticated programmable optimization engine-if youre an advanced user, you can rearrange the contents of your disk how you want.
- Defragment while the disk is in use
iDefrag can perform simple defragmentation while the disk is still in use. Good for situations where you dont need the full power of the optimizer, but have a few fragmented files you want to sort out.
- Per-block and accurate whole-disk display
See the individual blocks used by your files, watch iDefrag move them around in real time, and get an at-a-glance overview of the state of your disk.
- AppleScript and Automator support
iDefrag includes extensive AppleScript support and comes with an Automator action to help Automator users script defragmentation without needing to learn AppleScript.

System requirements:
- 500MHz PowerPC G3 or better.
- 512MB RAM.

Version restrictions:
- Demo version will not defrag disks over 100MB in size.

Enhancements
- Fixed a problem introduced in 1.6.8 where iDefrag was unable to move hard link folder files in Quick (on-line) mode.
- Added compatibility for PGP whole disk encryption.
- Updated the error messages for the on-line defrag routine.
- Prevent iDefrag from appearing to hang on completion when DNS is misconfigured (obviously its better to fix your DNS settings...).

TinkerTool System 2.0 has come as a combination of system utility features that assists you in performing advanced administration tasks on Apple Macintosh computers. The application makes use of a self-adapting user interface which automatically adjusts to the computer model and to the version of Mac OS X you are running.

All options available in the current situation are accessible via "panes", very similar to the techniques you already know from the System Preferences application. All functions can be controlled by a single program which acts as general toolbox and First Aid assistant.
