"We were all in a really good space," she said through tears.
Earlier, she told of how hard Macdonald worked for their family and how he spent more time with them after grievances were aired at a family meeting in 2008.
"He did want to look after us ... and always said he was working the long hours so he could provide for me and the kids ... It was all about me and the kids."
The tension was related to the amount of work Scott Guy was putting into the farm and concerns Macdonald had about being paid less than Mr Guy.
But while Macdonald quietly seethed about Mr Guy, a picture emerged yesterday of the simmering tensions Mr Guy was feeling about Macdonald and what he viewed as unfair treatment. In particular, he was concerned the Macdonalds were moving into the family homestead - a move he felt he was not consulted about.
The Macdonalds were in partnership with Scott and Kylee Guy, with the majority shareholders being Bryan and Jo Guy on the Feilding farm. Yesterday, Mrs Macdonald revealed her fears the arrangement would not work.
"I wasn't so sure, because I don't think three's a great number - two's company and three's a crowd."
She said Macdonald rarely spoke up when he was unhappy, usually letting her speak for them, despite her urging him to share his concerns with her father.
"He would say, 'It's your dad's farm and he can run it how he likes, it's not my place to say."'
She said there was competition between her husband and brother that "wasn't overly obvious".
Macdonald worried he was not getting paid as much even though he did more hours that were becoming "ridiculous" while Mr Guy left early to help his wife with their young son.
Mrs Macdonald told the court of her unease when at one stage Macdonald went into her father Bryan's office and checked the wage book.
"He wasn't taking anything but he was looking up, checking up."
The issues came to a head during a "tense" meeting in 2008 when Scott Guy came to a family meeting and dropped a bombshell - as the eldest son he expected to inherit the farm. Bryan and Jo Guy told him that was not going to happen but Mrs Macdonald was left shocked and angry by what she saw as her brother's unexpected "attack".
She said: "Scott came out very much on attack ... I was pretty hurt at the time."
Their father stepped in and spoke to Scott about it and suggested Mrs Macdonald wait a week before she responded.
When she did she was reduced to tears telling him how she felt about what he had said.
"He said things like, 'Why has Anna got stuff because she never worked a day on the farm,' and I wondered why I was being attacked."
Macdonald was "in disbelief" but said nothing during the meeting.
Under cross-examination, Mrs Macdonald said Macdonald and Mr Guy had been getting on better in the months before his death, and she thought her husband was making an effort to put the bad blood behind them.
"He said he was sick of coming home and moaning about them and said he would get over it and move on."
Mrs Guy yesterday described her husband as "one in a million" and the "most amazing husband and father".
On the issue of the Macdonalds moving into the family home, she said he wanted to be fair and not upset anyone, describing him as a "real softie" who was "not greedy at all".
"All Scott wanted was to be fair."
The relationship between him and Macdonald started well but was soon affected by their lack of communication with each other and with Bryan Guy.
"That was the main problem with the farm, was communication between the three of them," Mrs Guy said.
"Scott would try to bring [his concerns] forward and he just felt he wasn't being listened [to], no one took any notice."
While she gave her evidence Mrs Guy paused before saying Macdonald's name, then quietly added: "Oh, I don't even like saying his name."
