Hi there shai180, nice to hear from you.....again....
I thought I answered your question already, but here it goes again.....
Yes, there is an official apple electric cord, and it should be available in Israel, though, as you mentioned before, there are no official Apple stores in Israel..... There might be some stores that sell Apple products.....you can go to
apple.com/il (for israel, or choose the country from apple.com/ then under choose mac, then where to buy, type in your address, etc, and it will find you the closest store that sells Macs and other Apple products, including, hopefully, an Israeli Electrical cord...
That being said, you don't have to (but you can) buy a special electric cord for your iMac Pro. The original US cord with a plug converter will work fine, as all Macs will work from 100 v to 240 v, 50-60 hz, so anywhere in the world, really. And no, you don't need a 220 to 110 converter, just the plug converter or Israeli power cord will work fine. As far as I know, the electrical socket in the back of your iMac Pro is the same as any PC, which is really is, so you'd need a standard C13 PC female plug on one end and an Israeli electrical plug on the other end, of which there may be 3 types..... about the only small difference I could see between a standard PC C-13 cord (the Non Apple one) and the Apple one is, apart from the color, the little flange around the C-13 end of the cord where it plugs into the PC. I don't know how much difference that actually makes, though..... If you can find an iMac Israeli electric cord, and you know what type of electrical socket it will be plugged into, most of the modern ones use a 3 pin arrangement and the pins are arranged in a triangle......
then you should be fine
good luck to you.....
