You can either take notes in an app like Evernote (free from the App Store on the Dock) that keeps all data in a database or you can save individual documents and keep them in folders, such as "Chemistry 2014 fall". The advantage of Evernote is it is self-searching and self-organizing. It has the disadvantage of possibly losing all notes if the one database gets corrupt or damaged. The advantage of individual documents is you can share them with anyone and have better reliability.
For a Mac OS system, you have these popular options for individual text documents:
– You can open and edit .DOC or .DOCX files in TextEdit (included with Mac OS). You can also create reasonably good .DOC files with TextEdit. It lacks some of the more exacting formatting options found in the other choices below.
– MS Office 2011 (for OS 10.5.8 or later). About US$130.
– Apple's Pages that is like Word, and Keynote that is like PowerPoint; should be included with new Macs but for older Macs, buy each for US$19.99, click the App Store on the Dock. For your new Mac, if Pages is not in the Applications folder, click "App Store" on the Dock, and type "Pages" in the search. Download Pages.
– NeoOffice, newest version US$10, last year's version free. Some people use OpenOffice or LibreOffice, but they are lesser cousins to NeoOffice.
– http://Docs.google.com or other online office editors.
{NeoOffice is the direct Mac development of OpenOffice and LibreOffice, and thus has a better interface, smaller size, and better highlighting appearance. Most people learn about OpenOffice / LibreOffice from PC use, but they don't know there is a better free version for OS X.}
COMPATIBILITY:
– MS Office 2011 can edit and save any office document.
– Apple's Pages / Keynote / Numbers (sold separately) can edit any .DOC / .PPT / .XLS document, and export as .DOC / .PPT / .XLS document, but can only view .DOCX / .PPTX / .XLSX documents and edit / export them as .DOC / .PPT / .XLS.
– NeoOffice can edit and export any format of Word or PowerPoint or Excel document.
Pages is similar in use to Word, except not as many oddities and hidden defaults that are hard to change. Keynote is similar to PowerPoint, except with much better transitions. Keynote has two limitations: it cannot apply a video to more than one slide, and it cannot apply an audio file (music) to more than one slide (except as background for the whole presentation). That's why I have both Apple's office apps and MS Office.
