macOS High Sierra Patcher hdiutil error

Problem using macOS High Siera Patcher? How to fix hdiutil: attach failed - Resource busy

If you are an owner of an older Mac computer (in my case Mac mini Late 2009 - Mac mini 3,1), then you've probably wondering why has Apple denounced those older models in terms of Mac OS upgrade

Well, the stock machine is rather slow, the base versions had Intel's Core2Duo CPU's fom the P series that were mostly targeted to laptops.

Having just 2GB of RAM and a 5400RPM 160GB SATA drives made them a bit sluggish. When it comes to them running High Sierra, it would seem more like "walking" than running.

However, some of those machines can be upgraded to 8GB of RAM alongside a fresh boost of storage space in terms of nimble SSD.

Long story short, now you are able to install High Sierra on your machine by uinsg a macOS High Sierra Patcher created by dosdude1.

There, all good!

Cause of hdiutil: attach failed - Resource busy

Looking into building a USB flash drive with macOS High Sierra image I've ran into a problem that happened after the initial macOS High Sierra download and trying to add the macOS High Sierra to the USB drive.

The issue was with the hdiutil unabling to mount the image and thus failing the process by reporting the resource as busy.

The solution, outlined in the initial part of this article was found on GitHub when a problem appeared with Oracle's VirtualBox on macOS Sierra.

Hope it shines a little bit more light on the issue. Cheers!

If you can, donate!

One litte thing at the end. If you can and you are able to do so, donate. If you can't just spread the word.

Best FTP client: FlashFXP vs Transmit

So there isn't all that much to say about FTP clients, they are piece of software that helps you manage your files from your local machine to a server environment. In essence it has a simple job basically moving the files around while we keep trust that under the hood it supports most of the protocols (FTP, FTPS, SFTP, WebDAV, Amazon S3...) in order to make our lives easier.

So, when it comes down to it, the basics are the same, but the difference, for most people (developers), is in the workflow, and that comes down to speed and comfort of performing those file managing tasks.

I've been using FlashFXP for 10+ years and Transmit 5+ years (very frequently in the last two), so I believe I can give a pretty good impresion on how those two stack up.

One side note, both of the FTP clients are platform-only which means that FlashFXP is Windows, while Transmit is Mac OS X (now macOS) based. Some say its like comparing apples and oranges, right? Right? Thank you! Thank you! I'll be here all night.

True, the "eco systems" are different but the point is workflow and advantages and downsides of both apps. (Даље)

Како конвертовати DTS у AC3?

Како конвертовати DTS у AC3?

Овај текст је написан пре скоро 5 година (од времена објаве овог чланка) на Сервиио форуму, у периоду када су телевизори били много мање компатибилни са разноразним стандардима, а понајвише са онима за које је требала да се плати лиценца - као што је DTS.

Такође, велико хвала Југославу @yooyo3d за помоћ и инструкције.

Желео бих да са вама поделим туторијал који сам тестирао и за који сам се уверио да ради, а метода је бесплатна и једноставна.

Упутство је изведено на ffmepg-у за Windows 7 верзију 64 бита. Процедура је вероватно слична за Macintosh и Linux оперативне системе, али нисам имао прилике да тестирам, јер у тренутку када сам писао овај туторијал, нисам имао ни једног Mac-а у близини. Јебај га...  (Даље)

Adobe Dreamweaver REMOVE CSS

How to remove CSS properties from Adobe Dreamweaver CS3 and stop thanking people of Adobe by mentioning their nearest family in a sentence with fornication?

Seems that someone in Adobe, who is in charge of tag libraries, is not all that fond of acctually using his own software for work. So, for example, if you want to add a background property to a class or an id, you have to write almost a whole word so the Code Hint would jump over the backface or widow property that is in the way. True, you could use mid word letters but who wants to type kg for background?
