Backup software – Mac OS X

Backing up should be the most important thing you do.
Computers can be replaced but not your valuable data. 
When (not if) disaster strikes, having a backup can help get you back up and running quickly as well as keeping your data safe, by having it backed up to another location.

Apple Time Machine, which is a built-in feature of OS X is much better than having no backup at all, but might not suit all scenarios.

Below is a list of other backup software for Mac OS X
We do not make any recommendation or endorsement of any particular product, and this list will be by no means comprehensive, but hopefully one of these will help take the toil out of otherwise having to do manual backups.

Ink Jet Printers – replacement cartridge problems

Problems with replacement inkjet cartridges not working correctly can often be avoided by following these installation instructions:

  • Allow the cartridges to stand upright ( the same way they sit in the printer ) for at least a couple of hours before  installation
  • Do not shake the cartridges prior to  installation
  • Make sure that the yellow rip tabs are fully removed before installation and allow the cartridge to breathe for 30  seconds or so before putting it into the printer.
  • Do not tip the cartridges once the yellow rip tab  has been removed.
  • Fit the cartridges as a full set.
  • If the print pattern is poor after loading then perform up to 3 successive head cleans. If prints are still poor then switch off the printer (use the printer ON/OFF button not the power outlet) and leave  it for at least three hours to allow any trapped air to disperse before trying again.

Constantly removing and replacing cartridges that have already been installed, particularly with Epson printers, can cause problems as it will pump air into the system. The cartridges are not designed to be removed once installed.

WebBrowser for OS9/PowerPC

PowerPC’s which won’t run OSX reached their limit with OS9. A lot of these machines still work well and are capable of getting on to the Internet, but the problem is finding a suitable WebBrowser. Nothing seems to work with OS9 any more. But hang on – we found a couple which are free to download:

Classilla is a free, open source browser for Mac OS 9

Classilla is bringing back web browser support to your classic Macintosh — built on WaMCom, a port of Mozilla to classic Macintosh systems, using the same technology underpinning the popular Firefox browser. It’s completely free and it’s open source, and it’s standards-compliant. Use it without cost or restriction; or, if you’ve got the skills, hack it and make it your own. Classilla brings your wonderful old Power Macintoshes back to life and back online.

iCab 3.0.5 works with Mac OS 8.5 – 9.2.2

 

At least webpages should display much better than trying to use that old Mac version of Internet Explorer!
