Today I tried to copy files and folders off a USB hard disk (NTFS formatted) on my Windows 7 desktop. I encountered multiple files with permission problems. The manual method to change permissions is very tedious, so I created a script (DOS batch file) to do the same.

I got macOS Mojave 10.14 / 10.14.1 installed in Parallels very easily! But encountered some graphics issues with certain apps... and managed to find a workaround.

On my hosting provider, there is a slight tweak needed to get Grav to run on PHP 5.6. Here's the solution:

I've been experiencing this problem for a while - when presenting using Microsoft PowerPoint for Mac 2016 (version 15) on an external monitor (or LCD projector), PowerPoint used to both the presentation slide show and the Presenter View on my notebook display, instead of Presenter View on the notebook and the full-screen slide show on the external monitor. Recently, I found the solution!

I upgraded my iPad to iOS 11.0.0 last night - and this morning realized that my IBM Verse contacts had disappeared from my iPhone! I didn't update my iPhone, nor did I make any changes of significance lately. Most upsetting! Here's a guide to restoring your contacts.

Microsoft PowerPoint 2016 for Mac (aka version 15) has a strange quirk - when I copy and paste images from Preview or most other applications, the image gets copied in Tagged Image File Format (TIFF). The image is practically uncompressed (or possibly minimally compressed), resulting in very, very huge PPTX files! Plus: Removing unwanted font references.

It's pretty easy to get Picture in Picture (PiP) in Safari on macOS - just a right-click twice - and if that didn't work, I described simple workaround by disabling JavaScript. Here I have a Workflow.is App based workaround to enable PiP in YouTube in Safari on iOS. This allows me to surf (or work) while having a video running in a tiny floating window on my iPad.

So I got a new MacBook for work and I didn't realize upon next reboot, the enterprise profile had mandated FileVault encrypt the start up disk, and Apple had recommended an upgrade to macOS Sierra at the same time! You can imagine triggering both simultaneously upon reboot didn't go well at all!

Apple has noted that a number of users may experience an issue with iCloud setting being enabled after upgrading to iOS 10.3. For me, I had quite the opposite experience, as iOS 10.3 finally enabled some iCloud applications that I had never gotten working for a long time!

Recently I realized that the latest macOS Sierra 10.12 upgrade also updated Apache and PHP to newer revisions (2.4.23 and 5.6.24 respectively), but reverted to the default configurations. My previous post on Enabling Apache and PHP on OS X 10.11 needed a slight change too.

My Time Machine backups have started to take longer and longer to process and complete. I realized that excluding folders containing temporary, frequently changing and large files would quite dramatically speed it up.

Safari 10 on macOS Sierra has a useful Picture-in-Picture (PiP) feature to playback HTML5 videos in a small "always-on-top" window, just like on iPads with iOS 9+. To activate, just right-click a playing video and select Enter Picture-in-Picture. However, not all web videos seem to allow this, as they pop up their own menus without the PiP option. Here are two ways to try to enable PiP.

On my Mac, by default, the keyboard cannot be used to navigate and trigger dialog box buttons. To “fix” this shortcoming - enable Full Keyboard Access to use the tab key to navigate controls! But beware of downsides too...

I was recently at an office using a Ricoh Aficio multi-function printer. I downloaded the PPD Installer version 2.2.0.0 (dated 17/09/2014) for OS X 10.11 from the Ricoh Aficio MP 2510/3010/2590/3090 driver page. But no matter what I tried, the printer either could not be found or would print blank or garbled pages...
