Can't get more than one month of backups with Time Machine
I have been reviewing other related discussion in this forum and cannot seem to find an answer. It is possibly to do with residual pre-Intel programmes is the best I can determine, but the problem is how to find the culprits in my list of applications either remove them all together or transfer them to another HD I use for non-essential data and files. I have done this for a lot of other data and have added exclusions for some file that were giving me identified issues.
Would appreciate any suggestions as I'm getting a little frustrated at having to do a reset so often, and not being able have a greater time period of backups given that there was a time when I had nearly a year's worth.
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")
