![ZEN Movie, by Michael Green [1986]](https://i.ytimg.com/vi/lGRMW6ka9Rc/hqdefault.jpg "ZEN Movie, by Michael Green [1986]
Composed entirely of MacPaint images from his ground-breaking book, Zen & the Art of the Macintosh, Michael Green used MacMovies from Beck-Tech to assemble this stunning movie animation. When first publicly shown at the January 1986 Macworld Expo, Beck-Tech engineer Henry Spragens was so impressed he paid over $1000 for a 20MB hard drive just to be able to store and playback the movie on his own Mac. This and more can be found at Henrys website here: https://www.audioimprov.com/AudioImprov/Macintosh/Macintosh.html
💾 DOWNLOAD the original movie files here: https://macintoshgarden.org/apps/zen-movie

🙇♂️ Dear Subscribers and Friends,
I sincerely apologize for the delay in releasing my next product video overview. This ZEN Movie video is a smaller work that is my way of offering at least some content to you in July 2021.

![AMD 6970M Repasting & PROBLEM in 2009 iMac 27 [Video Card]](https://i.ytimg.com/vi/n2a8oEI2y6U/hqdefault.jpg "AMD 6970M Repasting & PROBLEM in 2009 iMac 27 [Video Card]
I explain a Radeon 6970M video card compatibility problem used in a late 2009 27 iMac. Repasting helps but doesnt completely solve the sudden power-down problem. (Sorry about the background noise, but thats Japan for you!)
🏥 PROBLEM: The 6970M causes the iMac to suddenly power-off when the video card gets too hot, unlike the stock 4850 video card which would never kill power to the Mac. Before repasting, the iMac would shut-off at around 52°C or 61°C, depending on the software running. After repasting (with Thermal Grizzly Kryonaut on the GPU and K5 Pro on the memory chips), the GPU Heatsink temperature at which the shutdown would occur became 77°C. This is still a problem though because the iMac shouldnt suddenly shutoff at all. I therefore cannot recommend the 6970M in 2009 or 2010 iMacs. I will retain mine though for further testing and to at least be able to use my iMac.
🎥 My previous video on the 6970M: https://youtu.be/9dPsH1zIQMs
👕 Apple T-Shirt worn in this video is a shirt Ive had since my college days, acquired sometime around 1990. Heres a photo showing the back side too: https://cl.ly/95c617
💳 EBAY listing of the 6970M I purchased:

🍎 Apple Forum Discussion about replacement video cards that work in the late 2009 27 iMac: https://discussions.apple.com/thread/3029120
♨️ If your 2008~2011 iMacs video card is dead and youve never baked it before, I suggest you perform the bake before spending the money on a replacement video card. My BAKE VIDEOS are here: https://bit.ly/2UEOf4o
🔥 THERMAL PASTES I strongly recommend:
K4 & K5 Pro Kit: https://amzn.to/38WkEZO
-or-
K5 Pro (for chips other than GPU): https://amzn.to/33OIDJ6
& Thermal Grizzly Kryonaut (for GPU only): https://amzn.to/36NMQwu
😎 Fan Control & Temperature Viewer Apps to keep your iMac running cooler I can vouch for all of these:
• Macs Fan Control: https://crystalidea.com/macs-fan-control
• smcFanControl: https://www.eidac.de
• iStat Menus: https://bjango.com/mac/istatmenus/
🛠 TOOLS to open/close iMac:
• 2 strong suction cups for front glass removal: https://amzn.to/2tkcmvJ
• Torx T10 for LCD removal (T9 works but T10 is best) & T9 for video card removal. The following kit contains more than needed for the iMac, but its highly rated, has grippy handles and magnetic tips, and no 1 month+ wait from China: https://amzn.to/2UCaurK
-or-
Alternative kit, WRENCH style (cheaper): https://amzn.to/2wIgWWe
-or-
Alternative kit, BIT style (youll need a handle): https://amzn.to/2vRkUeC
🔦 OTHER ITEMS needed or recommended:
• Anti-static wrist strap (connect wire to earth ground): https://amzn.to/2uSTy74
• Dust blower - Giottos Rocket Blaster Large: https://amzn.to/2OgHHXt
• Microfiber cloth (for cleaning the screen/glass)
• Flashlight (to peer into the dark spaces inside the iMac)
► I used a Samsung EVO 850 1TB SSD to replace the stock Apple hard drive, but the 860 EVO or Crucial MX500 are equivalent. To use an SSD in late 2009 27 iMac, youll also need a special mounting bracket and a separate temperature sensor:
• Bracket: https://amzn.to/37Zn4qg
• Sensor for 2009-2010 iMacs: https://amzn.to/3b3knWU
• EVO 860 (1TB): https://amzn.to/2RKem9M
-or-
• Crucial MX500 (2TB): https://amzn.to/3bxHybf
