Enable pf at startup on Apple macOS, SIP enabled
After searching for a way to enable the built in pf firewall at startup in High Sierra (I didn’t want to additionally enable the Application Firewall, just the packet filter piece) I found many posts that all mentioned disabling System Integrity Protection (SIP) and directly editing the default launchd file:
Yosemite and Apple Mail
This fixed a huge issue I had with Apple mail:
Edit: Apparently the author is going through an existential crisis of some sort and has removed the post; the long and short of it was to disable (uncheck) the setting for “Automatically detect and maintain settings”.

iCloud vs. Snow Leopard vs. Windows 7
I have been using MobileMe since Apple started the service to keep my contacts and calendar in sync across all of my devices wirelessly. Except for a few hiccups early on, it has been a great solution to keep all of my information with me all of the time — on my iPhone, iPad, Windows 7 PC and a Macbook Pro running Snow Leopard (10.6.8.)
MobileMe still doesn’t support Outlook reminders
Apple’s MobileMe is a great idea. It has been the only real answer to keeping contacts and calendars synced across multiple Apple devices (iPhone, iPad) and multiple computers using both Windows and OS X. Despite a rocky start (see this article) the service has gradually become better and better. But a problem developed for Outlook users when Apple moved to a new calendar format. The upgraded calendar no longer synchronizes your local Outlook calendar with the MobileMe remote calendar (including your alerts/reminders) — instead you get a second, external CalDAV calendar linked in Outlook and stored “in the cloud,” separate and distinct from your local Outlook calendar.
