I`m disappointed that I have not received adequate support from the Netgear Community. I will try customer support however should not be made to pay when there is no problem with the software or hardware.
You have given very few details concerning your issue. "It comes up with an OS error" is like calling an an auto mechanic and telling him simply "my car doesn't run" and expecting him to diagnose your problem over the phone. In addition, many of us don't use a Mac (myself and @StephenB are major posters, and neither of us do), so can't help even if you give details.
You can start with these: Is the error on the NAS or the Mac? What is the error? What NAS user name are you using (admin, or your own account)? Did this start happening when you updated the OS on the Mac or NAS, and if so, from what to what?
Your non-descriptive subject, which doesn't even mention Time Machine, certainly doesn't cause anyone who might know the answer to look at this post.
Apple apparently makes changes to Time Machine all the time and just expects other companies to keep up with them. Or maybe they hope other companies won't, forcing you to use their products exclusively. I've come to that conclusion based on other posts here similar to yours, but much more descriptive. So, maybe, you'd get a better answer in an Apple forum.
Start by helping forum users understand the specifics of your issue, and maybe you'll get better responses. But this is primarily a user-to-user forum, and your attitude of just expecting a solution from a fellow, unpaid user is not going to gain you friends here. @JeraldM does work for Netgear and did start trying to help you, and you didn't indicate you did read the article he pointed you to nor did you post the information he asked for. I can certainly understand why he would abandon trying to help you when you won't even help yourself.
I have acknowledged your feedback and comments. I appreciate that my initial post was lacking in detail however this should be sufficient baseline to start a discussion. The Netgear Community site has limitations despite best intentions of other users. I`m concerned that a user had replied to your comment to express their disatisfaction which was subsequently removed. I believed users have the right to express their opinion which you have made clear to myself and to Apple users. Perhaps it will be useful to have guidelines when writing a comment before it can be completed and posted.
To clarify, neither @Sandshark nor I work for Netgear. We don't represent them in any way, and are not responsible for their moderation policies.
Netgear's direct engagement in the ReadyNAS forums has dropped sharply over the past few years, and the mod who did respond to you has since left Netgear. Although Netgear hasn't said, it's clear to me that Netgear has been quiet-quitting the NAS business for some years, and I think the barriers in getting customer support is part of that.
My experience here suggests that if you do want other users to chime in with suggestions, it is best to offer more details in your initial post, and not require folks to ask. Though since I am not a Mac user, I have no direct experience with TimeMachine, so unfortunately have no ideas on how to resolve your particular problem.
Thank you for your input. It`s disappointing that Netgear have reduced technical support for customers unless it`s paid for data recovery service as indicated in an email response from an advisor. That said, it seems I may ave resolved my technical problem. My MacBook has access to Time Machine saved on ReadyNAS. However, there continues to be an error initially when attempting to back-up and after numerous attempt it`s successful. Interestingly, my ReadyNAS continues to indicate on the display that it cannot find the IP address. I`m connected to ReadyNAS via ethernet cable and use RAIDar. This problem started following moving house and subsequently changing router / IP address. I will appreciate any technical support.
