OS X has a built in application that lets you open and read pdf files. It is called Preview. If you click on a pdf file it will automatically open in Preview.
Thankfully with OS X Yosemite (OSX 10.10) it’s really easily merge 2 pdf files with the built in OS X Preview app.
From within preview you can add more pages to the pdf file. When you save the pdf file these extra pages are combined so that all the extra pages are merged with the original pdf.
Apple don’t have instructions for how to do a clean installation of OS X Yosemite, but it is exactly the same as the previous version of OS X – Mavericks. So if you want a clean fresh installation of Yosemite, just follow Apple’s instructions here of Mavericks”

Yosemite has just been released. Like any new OSX, it has various problems with the first release, so unless you really need it, I’d wait for the first minor update to come out to fix some of the buys.
If you decide to install Yosemite, here are a few things to be aware of before you upgrade.
The first three weeks of Yosemite has been painful because Dragon Dictate has not been working properly. It would not read my old profiles and would not let me train a new one without crashing. I rely fairly heavily on Dragon Dictate to do most of my writing/typing so this was a bit of a dud. I was going to write a post on a workaround for this problem, but Nuance released an update today – version 4.0.6 – which fixes the problems. Training is working again and Dragon Dictate has stopped crashing.
Nuance should have had this all worked out before Yosemite was released, but at least we are back in business now.

Some SSD drives are crashing in Yosemite do to an issue with something called ‘TRIM’. Thankfully if you followed the method in my article entitled “How to speed up your mac with a Solid State SSD Drive” you will not have this problem. But if you have used an SSD that needs TRIM, read on to find out about the problem and how to fix it.
The upgrade to OS X Yosemite broke my Fuji Xerox Docu-centre C4300 laser printer. When I tried to print it gave me this error: “Filter Failed”. Here is how I eventually fixed it.
